We did multiple roadblocks to block access to any of the backstop area. The odds of somebody appearing in our backstop would be about the same as somebody walking over the top of the backstop at your local, 1 shot per second, sight in your deer rifle range.
Anybody who crested the top of the hill was immediatly stopped, and told where we were shooting, and how we had the backstops set up.
Hoplo, your smugness is so thick I could cut it with a chainsaw. I've got 40 people who were actually there who disagree with you. Then I've got you, who weren't there, telling us that we did it wrong. Uh, I'm going to go with the people that were actually there.
Did lines get staggered? Possibly. That happens in the real world. When it does, you correct the behavior. If the shooter is unsafe, you remove them from the line.
There is an element of danger anytime weapons are manipulated. You do what you can to maximize your safety, and minimize potential problems.
Or you can occasionally shoot one shot per second, at your local hunter's ed range, where you place all your stuff on a bench, don't work from a holster, and have a range officer to scream at your every move. (which by the way, from what I've seen as an actual certified safety instructor, ingrains far worse habits in shooters than just running a hot range).
And edited to add: PvtPyle and I always have a brainstorming session after any gun related activity to see how we could do things better. I do not want to give the illusion that we think we know it all, or are infallible. We address each concern, safety or otherwise, and plan for the next shoot.
So that is perhaps why your unfounded criticisms were so galling. We will be implementing improvements for the next one, but sadly, most of the things you've pointed out as issues didn't exist.
