Brimfield Antique Show
Three times a year, the 18th-century town of Brimfield is overwhelmed by a series of antiques shows set up in humongous open fields for a six-day stretch. Virtually anything you collect, no matter how obscure, will likely turn up among the merchandise at the 5,000-odd tents. A word of warning: Book your accommodations early (vendors have been snagging the same hotel rooms for decades) and bring a flashlight (shows start at dawn).
May 11–16, July 13–18, and September 7–12, 2010; from dawn until dusk.
