Usually big arena’s like this do not allow conceal carry so this is not a problem for me. When I go to the mall, which is very rare, I always know my exits, I pay attention to the carts set up in the middle of the mall, If it is early morning or later evening around closing I am careful about being in isolated areas as most malls are pretty desolate around me. Many stores have went out business and there is a lot of empty places. In Restaurants I never sit with my back to the door and always make sure I can see the door or front of the restaurant and know my exits . In parking lots I walk slowly past cars and never close them. I do not let my son get in the drivers side until I make sure no one is over there and after I check and make sure he is in and the door locked, then I put groceries in the back.
No matter where I am in public I always look for people acting nervous or out of place. Even at the Walmart one town over which is a nice area, lots of crazy stuff has happened in the parking lot. Carjackings, flashers, some lady trying to get my husband to go back in the store with her, scams, you name it, it has happened. People have been shot leaving the ball game in St. Louis and other events. You can never be to careful anymore.
