This sounds fun — an all-volunteer community potluck picnic and Smorgasbike event that gives you a chance to ride all sorts of bikes, among other fun things.  The Try-a-Bike Jamboree is Saturday, July 2, from 10:00 a.m. – 1:00 p.m. at the Washington Blvd Bud Harris Cycling Oval, 1401 Washington Blvd, in Pittsburgh.

This event is free; helmet and waivers are required.  Parking is available and they say that bike-based tailgating is strongly encouraged.  For more information, look at Bike Pittsburgh’s page, or the Facebook event page.
