Around St. Ratrick's Day 2005, a bunch of Rats moved into a building in Chicago's Humboldt Park neighborhood that came to be known as "Pot'n'Rocks". It was only natural that the local kids would come around with bikes to fix when they saw us working on ours. What started as a few kids hanging around the stoop has turned into Bike Club, a junior version of the Rat Patrol that teaches bike mechanics to Humboldt Park kids in the 12-17 age range.
