The article has good points. Being too fearful is one. Although vigilance and awareness are sensible states to maintain, hyper-vigilance may not be warranted. I go lots of places that I can't carry a weapon. Medical offices and hospitals are two. My dentist's office does not have a no gun sign, but I choose to lock my handgun in my truck's tool box when I go there. When I have worked out at gyms, I saw no reason to have a weapon. I make such decisions based on perceived risks. I try very hard to avoid places with risks. Under no circumstances will I carry a weapon where doing so is illegal. If I can't live with that choice, I don't go there.
