I'm always amazed, when this subject comes up, that this subject actually comes up.
I've never had a complaint when I lay down a ground cover/smoke curtain. I usually get a few laughs and maybe a couple of "wtf was that!!?"
I'm pretty sure I would ignore any complaints as they would not be coming from real gunnuts. If you don't like flame and smoke and loud noises, maybe you'd be happier to take up golf?
If there are the studious/earnest/ marksmen types on the line, as a courtesy, I would let them know that there's "fire in the hole" LOL But that's about it.
