Hey, it sounds like a good idea indeed.
Honestly, being a Thursday night, you might want to consider a suburban venue, as it would be a lot closer for folks staying around Joliet. Tailgaters in Bolingbrook would be perfect as it is right off the 355.
Shark City would be awesome, not just because i live 10 minutes away from it or anything....
I'm coming in on Thursday, so I'm down to see more bands that night.
You staying in the city or Joliet?
