Last time I was at Joliet was in 1999 if I remember correct, it was the CarCraft Nationals.
Ended up being a small riot and stuff downtown cuz of all the cars doing burnouts on a side street in front of a hotel. There were a few thousand people spectating along that route just watchin the cars.
Police came out in riot gear and started arresting the drivers, had like 3 helicopters, and started throwin the tear gas....that was a crazy night!!
