FROM MAY 31: WELL, the city of Beacon is now 90 years old and today a major modern art museum is opening here. Dia:Beacon is opening in the old Nabisco plant down by the train tracks and you can read about it in the New York Times, Poughkeepsie Journal etc. I havent seen this many out of state plates in years and Main Street is crowded with people, including one guy dressed up in a chicken suit trying to haul the passersby into Planet Wings. I cant imagine where all these people are parked, since Beacon is not chock full of free parking. Our happy little burg is now a major attraction for art and antiques. You wouldnt think that a small American city could base its economy on selling Grandma's old furniture and art that no one understands, but you would be wrong.
