Simple things can help. My daughter and 2 grandchildren were recently up from Florida. The last time I was down there, I gave her a revolver and shotgun and took her and her husband by their local range. Anyhow, I stressed to her yesterday, on your way home (or anywhere really), don't just walk out the gas station door and start moving. Take a second to scope out the area you are headed for. If things look suspicious, go back inside and wait awhile. Know what you are walking into before you get there.
