Reading through this thread makes me think it was worth it, working my tail off to have a place where the benchrest is on the front porch and the pistol range is in the back yard. Defintely worth it, all those years!
I dunno, though. If I'm gonna do rapid fire with a brass thrower, I'm gonna work with the neighbors on the downstream side. Warn'em, give'em a chance to step back, some such deal. Preferably, of course, be on their off side so it's no problem, if possible.
Or, wait a while until some space opens up, if people are in the "coming and going" sort of process...
Common courtesy, seems to me. Seems to be in short supply, these days.
