Brimfield Antique and Collectibles Show
The organizers claim this to be the world's largest outdoor antiques event, with more than 6000 dealers and 130,000 visitors. From the website: "While it is convenient to refer to it as 'The Show,' it is actually comprised of 23 fields, owned by 'Promoters,' who lease spaces to dealers from all over the world." They're spread over a mile on Route 20. It's held three times each year. The town is about 25 miles west of Springfield, Mass.
