When we came down from the 94th floor of the Hancock Tower we thought we'd walk along Michigan Avenue to take in the sites. Just along the sidewalk from the exit is this trash can full of old shoes. Now some of them look to be in pretty good condition, but search as I may I have not been able to find any information on how they got there and why? I have two thoughts on why and how they are there. One, that it is kind of shoe tree that appears all over California and I'm sure the country, where people just for fun hang their old shoes. Or two, that people leave their old shoes that aren't in such bad condition, so that homeless people can take them. Anyone got any other ideas, let me know.
