Chicago Distance Classic 8/12/07
This is a far-off shot of the Hi Guy. I see him biking along the lake path all the time. I'm not sure about his story (like, why he does what he does), but I know he's run a ton of races. I saw him around mile 3 of the half marathon, and I noticed he was wearing these special-looking sandals.
