Since 2004 I've lived in the gang-ridden Humboldt Park neighborhood of Chicago. It was only natural that neighborhood kids would come around to have their bikes fixed, and so before long I had a regular event on my hands. We called it "bike club" and we'd teach kids how to fix bikes, build up bikes with them to give out, and weld custom bikes that they had designed.
While my job has me traveling a lot more these days, I still fix up and give out as many bikes as I can, and can't stay in one place for long before every neighborhood kid knows my name. Eventually I'll grow my Ghana project enough that I can fund an arm of it in the U.S. inner city where it is equally, desperately needed.
