Maybe a dumb question, but here goes. A few years back when I had my carry permit, I was going into the Sullivan for one of the shows there (maybe the Sportsman Show). On the door they had a sign with a gun that basically said it was illegal to carry a firearm in the building and then sighted a law number. I never looked it up, but it still makes me wonder. When taking my class I remember them saying bars, federal buildings, schools, secured airport areas, etc. Was it legal to carry with a permit into the Sullivan?
