I'm not sure that Illinois will make the jump from no provision for CCW to allowing carry on campus, but I certainly wish them luck. When I'm trying to go somewhere from Indiana, I avoid at all costs going through Illinois, because my right to carry my firearm is worthless there.
When I fly though Chicago on my way between TX and IN, I've often considered what would happen to me if I had to retrieve my luggage due to a missed plane, or some other problem. I would hope that I'd be covered under Federal Transportation Laws, but I certainly don't want to end up as the test case.
Goodluck it Illinois, if they pass a shall issue law, and will recognize my Indiana permit, I'm far more likely to visit the state!
