I just saw this in a post and I had been searching for days to find it. A U.S. map put together by peoples experiences and knowledge showing what businesses allow guns and which ones do not. It took me forever to find it so maybe this post will help other newbies such as myself out. I added the locations I knew YES OR NO about in my areas and urge everyone else to do so. Knowing ahead of time is great.
