A local convention center has a gun show every few months. And the parking lot is always PACKED. I'm kind of curious how these things work. As far as I know you need to have a background check (and presumably a "cooling off" period). Is that to get a FOID card? Or to buy a gun? If it's to buy a gun do you have to have one every time you buy a gun? If someone has an FOID card and goes to one of these gun shows can they buy a gun and take it home? Or is it kind of like a car show where dealers go in hopes of getting you to come back to their store to buy? How does it work with kids that go hunting? Do they need FOID cards? Can they buy their own guns? Or does a parent with an FOID card buy the gun and the parent is technically the owner of the gun?
