The last time I was at BH I called "Range cold!" during a lull in shooting. One of the guys on the line looked at me like, "Huh? It's pretty warm out here." Seeing his puzzled look I followed up with, "I want to check my target, so no shooting. OK?"
"OK."
A couple of other people and I went downrange and tended our targets. When I got back to the line this Deliverance looking bubba said, "I could see you real good - I was watchin' you in my scope."
I packed up and left, and joined Palmetto Gun Club.
