My view

GRPC in Chicago,  yes they chose it as it does not allow its citizens the right to arms.

I did have a conflict in my own schedule, but I'm also not going to attend an event that I have to deprive myself of my rights, or contribute money to a place that wants to deprive me of my rights. It was not the event itself, as with the NRA in Charlotte NC the venue was questioned, but at least in traveling to the event, in the motel etc I could still have the right and means of defense, but traveling into a state and a city that forbid it was my issue.
