I wonder, what is your way of keeping cool during the crazy, heat wave that has kept us prisoners these past couple of weeks. Movie theaters? Shopping malls? My secret is museum galleries. On Sunday, when the temperature hit 100 degrees and the humidity, I swear, approached 150% I escaped to the Hammer Museum. It was heaven to spend a couple of hours walking through ---The Soci--t-- Anonyme---, the coolest show in town, telling the story of modernism in America. Besides, the Hammer announced that during the whole summer admission to the Museum is free. How cool is that?..
