i have to disagree with most comments. You could ave run out there and let the guy knows. Most times folk go OPPS i messed up and thank you.
Now I can agree that if that does not work than tell an R/O. (I are one a 2 ranges)
Now we I am busy I do not have time to check on outside much if at all.
And it is YOUR responisibilty to maintain yourslef and others to the 4 COMMANDMENTS of firearme safety.
I understand what you are saying but you have to get a FAIL on this one.
Having said that i think the range needs a FULL review of thier safety procedures.
