I have always answered the door with a weapon readily available. The one time I regret was two mormon "misionary's" came to the door. I was cleaning my rifle and forgot to put it down before opening the door. resulted in two really scared mormon's. I apologized to them and spent a couple minutes talking to them, I try not to scare people actually trying to do good with my precautions. By that statement I have a local high school up the street so I get hit up for fundraisers for the different events. I gladly try to support the bands, sports teams, and other activities keeping those teenagers occupied.
