So I was walking down Michigan Avenue the other day and I ran into the "Walking man."  Well, he looked awful.  His hair was messed up and turning gray, his clothes were a mess, and worst of all he wasn't walking, I mean really striding out there like he used to do.  He was almost stumbling along.  I don't know if he is sick or drugged or what, but it was very sad and disconcerting.
If you're not that familiar with him, I found this site on the web:  http://echochicago.blogspot.com/2005/04/walking-dude-by-slippy-jenkins.html
