From time to time we hear stories about a person that is murdered at a range and his weapons then stolen. Although I have never experienced this (obviously) I have been to some ranges where I tarted having some bad feelings something wasn't right. These would be the ranges where there is no RO on sight and it is self policing. Although it wouldn't seem so, you are vulnerable. You have ear muffs on and are focused on single line of sight. Most times you are by yourself with a wide array of equipment spread out all over a table and sometimes the ground. What do you do to protect yourself in this situation?
