Seems like there at THREE swap meets this weekend.

35th Annual Ann Arbor Classic Bicycle Show and Swap Meet, Ann Arbor, MI

Memory Lane Spring Classic Swap Meet, Grand Rapids, OH

Midwest Bicycle Swap - Coasters Bicycle Club, Wichita, KS.

I have no experience with any of them, do any of you know what to expect from any of these?
I need to pick one, im hoping to sell AND buy... mostly Classic and vintage road bike stuff
