I don't have any pictures of my first bike - it was a cheap blue thing from Wal-Mart. I rode it until I was physically too large for it, much longer than I imagine the manufacturers could have planned for. By the time I was done with it, the paint was sun-bleached and the metal was rusty and pitted from spending so much time outside (I had a penchant for forgetting it at the playground)!
That's not much of a story, but I had to contribute something before I said how much fun it is imagining all these internet personalities as pudgy-faced children. goobster's Huffy Dill Pickle is what really got me - I knew a kid with a bike like that, and he permanently had chocolate stains on his face. Sorry goob, that's probably going to stick as my mental image of you!
