We used to get a bit crazy with the local IDPA shoot, but ideas still apply.......
Werewolves anyone?
Headshots on "zombies" with ripped T-shirts as dressing........You had to retrieve your car keys to escape.....
That fake spiderwebbing you find this time of year makes a nice partial vision barrier and withstands bullets like a champ.
We also tied some toy axes to swingers and had them attack "no shoot" targets.........
Yeah, we had way too much time on our hands......
