While Bridgehampton isn't quite Bilbao, opening a museum has become the newest fad in town. More boards, more fundraising, more parties. Since long before this recent spate of philanthropic patronage, the Dan Flavin Art Institute has quietly occupied a little-known spot in Bridgehampton.  It's a charming, barn-like structure that's actually an old firehouse, practically across the street from Candy Kitchen. Perfect for when you want to force some culture on the kids before they get their chocolate milkshakes. 

Kids like colored light bulbs.  Just walk in—the tiny museum is free and a visit is quick. You can leave your stroller downstairs. Upstairs is home to the Dan Flavin collection: nine installations, all fluorescent bulbs. Special exhibits are housed on the first floor—this summer, it's Fred Sandback prints. The museum is located on Corwith Avenue; it's only open Thursday-Sunday 'in season', meaning May 25-September 17—so you're on deadline.
