At the World Cup viewing party in Grant Park, I locked my bike to a short, black metal decorative fence that borders flower beds on the sidewalk with hundreds of other bikes up and down Columbus, on both sides of the street. I am sure this was not a temporary fence. Came back around 11pm to see that ALL of the bikes were gone, not a single one left on the fences and a lot of the fences had their black paint peeling when I'm pretty sure they hadn't before. I would have thought this was a regular stolen bike but there were SO MANY bikes for the entire block, both sides of the street, when I parked it and NOT A SINGLE ONE LEFT when I got back, I really don't think I was the last person to go back for their bike, especially given the crazy traffic and loads of drunk people. I went so far as to call Grant Park security, CDOT, the Park District and CPD hoping that my bike was impounded or something for being technically illegally parked but none of them claimed responsibility. It just seemed so weird that the WHOLE street was cleared from bikes were not many hours before there were hundreds. CDOT noted the paint all of sudden could come from the sparks of an angle grinder.
