Brimfield - it's a wonderland of antiques! There are fields and fields of finds. There's art, furniture, fabrics, jewelry, kitchen and home goods, clothing, and lots of collectibles you didn't know existed. The show happens 3 times a year in Brimfield, Massachusetts, in May, July, and September.

A few tips for first-time show goers:

Make hotel reservations early as they book up fast. We found that we needed about 2 full days in the market (but we went for 2.5).
Bring cash for parking and for negotiating (there are ATMs there, but you'll want cash in your car for parking).
Bring water and snacks. You'll be walking a lot and it can be quite hot, so you'll want to stay hydrated. There is plenty of food there, so you won't go hungry, but carry something with you if you find you need to nibble.
Have a strategy for carrying your finds. Vendors will have bags and some wrapping supplies, but depending on how often you want to go back to your car, you might find yourself in a situation where you are carrying quite a few precious items. You can carry your own bags, or a rolling cart, etc...
