Gretchen told me about this go-kart track in Braintree that features Formula-One looking cars:

F1 Boston is New England's hottest, most complete entertainment and function facility. Whether you're building corporate team spirit, launching a new product, entertaining a new client or just want to come in and race at F1, power is at your command. You'll find state of the art exhibition and conference facilities...full-service restaurant...classic billiard parlor...shops...lounges... and, of course, racing.
