>Public service announcement: While I was in a Denver gun store today, my car
>was tagged on the wheel in the parking lot. The gangs do this on wheels or
>bumpers at gun stores, shooting ranges, gun shows etc. Later when you are
>parked at a restaurant, hotel, or other location that’s less well guarded or
>under video surveillance, other gang members spot the marker and break into the
>car for a quick gun grab. This is so RAMPANT in San Antonio where we were for
>a National shoot this summer, the police chief of that county came out to brief
>the 400 participants of our competition. Too bad three teams had already
>been victimized the first day. This is the first I’ve heard of this in Denver .

>I don’t know how widespread this is becoming , but the info regarding the NSCA
>Nationals in San Antonio is correct, as all of us who compete in sporting clays

>Some crews were working the parking lot at the Nationals itself. 27 high end
