Travel guru, Arthur Frommer, says that now is the best time to travel in 20 years, thanks to a combination of a strong dollar and desperate price-cutting forced by the recession.

Five years after oil hit an historic peak at $148/barrel, when $500 fuel surcharges abounded, and the demise of the travel industry was widely predicted, costs in some countries, like Mexico and Costa Rica are 50% lower than a year ago. Talk about price elasticity with a turbocharger!

Frommer believes there are three sea change trends going on today. Business is moving away from the big three travel websites, Travelocity, Orbitz, and Priceline, who have more preferential side deals with airlines than can be counted, towards pure aggregator sites that almost always offer cheaper fares, like Kayak.com, Momondo.com, and travel.yahoo.com.

There is a move away from traditional 48 person escorted bus tours towards small group adventures, like those offered by Gap Adventures, Intrepid Tours, and Adventure Center, that take parties of 12 or less on eye opening public transportation.

There has also been a huge surge in programs offered by universities that turn travelers into students for a week to study the liberal arts at Oxford, Cambridge, and UC Berkeley. His favorite was the Great Books programs offered by St. Johns University in Santa Fe, New Mexico. He says that the Internet has given a huge boost to international travel, but warns against user-generated content, 70% of which is bogus and posted by the hotels and restaurants themselves.

The 82-year-old Frommer turned an army posting in Berlin in 1952 into a travel empire that publishes 340 books a year, or one out of every four travel books on the market. I met him on a swing through the San Francisco Bay Area (his ticket from New York was only $150), and he graciously signed my original 1968 copy of Europe on $5 a Day, which was crammed in my backpack for two years.

Which country has changed the most in his 60 years of travel writing? France, where the citizenry have become noticeably more civil since losing WWII. Bali is the only place where you can still travel for $5/day, although you can see Honduras for $10. Always looking for a deal, Arthur?s next trip is to Chile, the only country he has never visited, because the currency there has crashed. Sounds like a man after my own heart.

?I have to admit that it was with some trepidation that I joined Supreme Court Justice, Sonia Sotomayor, for lunch in San Francisco. I have friends in the New York federal prosecutor?s office who warned me that she was tough as nails and a complete bitch, first as a prosecutor herself, and later as a judge.

I confided this observation to her, and she agreed completely. Growing up as a poor Hispanic girl in the South Bronx, with a single parent family, demanded more than toughness. Her father died young from chronic alcoholism.

As a kid, she beat up a lot of others, but was thrashed often herself. It was certainly no place for weaklings, or those who stuck to establishment rules. Her family nicknamed her ?ahi?, Puerto Rican for ?hot chili pepper.?

Interviewing Supreme Court justices is a tough game, as I learned when I met Sandra Day O?Connor a few months ago, the first woman ever appointed. But at least we had some common ground, both growing up on ranches in the baking Southwest before air conditioning was invented. The great insight with her was that on her first day at work there was no woman?s bathroom at the Supreme Court. Sonia Sotomayor would be a different kettle of fish.

Justices are not permitted to comment on any cases in the recent past, present, or those that may appear in front of them in the future. And by recent, I mean in the past 12 years. You really have to go back to Andrew Jackson for them to feel totally comfortable.

Back then, my own family took a case to the court on the interpretation of the India Removals Act of 1830. We won. (The government was not allowed to banish a white woman married to an Indian chief west of the Mississippi). So the best that you can do is try and get the measure of the person, their character and their motivations, and distill down their essence. Then you have to extrapolate forward as to how this may influence their future decisions.

You might ask what this piece is doing in an investment newsletter. But the Supreme Court is playing a growing role in the lives of traders. The decision in favor of Obamacare totally upended the entire health care industry, which accounts for no less than 12% of our GDP, and will soon rise to 18% (You sold the HMO?s and bought the drug companies).

The Citizens United decision permitting unlimited anonymous corporate political donations was a boon for the media and the Washington DC commercial property market, as tens of thousands of new lobbyists were hired. Bush v Gore, which decided the 2000 presidential election, turned out to be the greatest windfall in history for the oil and defense industries. Investors ignore the Supreme Court at their peril.

Justice Sotomayor frankly admitted to me that she was an early beneficiary of affirmative action. But she ran like thoroughbred, once the bit was between her teeth. She was one of the first women admitted to Princeton, which proved to be a totally alien environment. There she heard a Southern accent for the first time. The looking glass metaphors in Lewis Carol?s Alice in Wonderland were unknown to her. It was not part of Hispanic culture.

When invited to join Phi Beta Kappa for her academic excellence, she thought it was a scam. They asked for money for a lousy symbolic key, so she threw it in the trash. Sonia rarely slept, graduated Summa cum Laude in 1976, and moved on to Yale Law School.

Racial slurs, sexism, and discrimination, feature large in her life. When she worked as a corporate litigator, a senior partner complained that he didn?t know why the firm was hiring all these minorities, only to dismiss them for incompetence a few years later. I hope this guy isn?t planning on pleading any cases in front of the Supreme Court in the near future. In fact, Sotomayor will have to rule on a reverse discrimination case brought by a white college student some time this year.

Sotomayor is one of those rare individuals who walk a fine line between both political parties. She was appointed a federal judge by George H.W. Bush. She was moved up to the Appeals Court by Bill Clinton. Obama named her as his second Supreme Court appointment, and only the third woman in history.

I think the majority of observers missed the most important outcome of the 2012 presidential election. If a conservative justice dies or retires before 2016, and another liberal replaces Justice Ruth Bader Ginsburg, the impact on history will be huge. Then, the court swings from a 5-4 conservative vote, where it has been for the past 40 years, to 5-4 liberal for the next 40 years.?

Sotomayor is a crucial part of this plan, and is so far following the script. In her first case, during which she confesses she was ?terrified?, she dissented on the above-mentioned Citizens United case. She has voted with left leaning Justices Ginsburg and Stephen Breyer 90?percent of the time, one of the highest agreement rates on the Court. She was in the 5?3 majority in Arizona v. United States that struck down several aspects of the state?s anti-illegal immigration law. She was also in the 5-4 majority that ruled in favor of Obamacare.

The US Supreme Court is a world stage, as its decisions are closely followed by the judiciaries of many other countries. It is a non-stop conversation in which she walked at mid point. Sonia says most people would find her job boring, as it is very contemplative. The court only hears 60-80 cases a year, and allocates just an hour to hear arguments for each case. The rest of her time is spent reading, writing, editing, and arguing with other justices.

The reality that there is no higher court than her own places an additional burden on her decisions. It is all humbling, as every case produces someone who, in the end, believes an injustice has been done. You can?t play God. Sotomayor is the only member of the court who has worked as a judge.

Sonia revealed to me that her inspiration to go into law came from the Nancy Drew children?s mystery novels and the Perry Mason TV series. Chronic type 2 diabetes prevented her from working in the field. For her, being a lawyer enabled her to work as a detective while in the confines of an office.

On January 21, Sotomayor administered the oath of office to Vice President, Joseph Biden. Not bad for someone who claims her main accomplishment in life was throwing the opening pitch at a New York Yankees game in her hometown Bronx.

As our lunch broke up, she invited me to Washington to tour the Supreme Court and meet the other justices. I said I might just take her up on that.
