One of the problems that CCW permit holders encounter is the occasional "No guns allowed" sign on the door of a store or restaurant. Most of the time we just go somewhere else, but it would be nice to know ahead of time if our proposed destination does not allow firearms. There is an Android application, still in its infancy, that will supply that information. Some bugs to be worked out, and in need of more data. Of course, now all a predator has to do is get one of these lists and they know the places where they are least likely to meet interference.
