It's kind of like a barn dance except small communities have a band and usually rope off a block or two of the small town to dance and drink. They are very fun and, unfortunately, seem to be disappearing from Americana.
When I grew up in rural South Dakota it was not uncommon for there to be a street dance in some small town somewhere in the state every weekend of the summer. We would even drive up to 100 miles to attend one. They were/are a blast. It was also the best way to meet young girls who weren't exposed to your daily reputation in your own small town.
Oh, and the fights. Testosterone fueled youths full of beer trying to show that our town is tougher than your town. Ahhh great memories.
