I shot a couple 3D shoots about a year or two back and I had poor experiences. It was the same as any disc golf, bowling, or regular golf tournaments I’ve been in. Everyone takes it way too seriously, they take forever, and act like pricks if you’re new.

20 targets shouldn’t take 4-6 hours to shoot (even with a shot gun start). Range the stupid thing and shoot.
I enjoyed shooting 3-D targets, and I love competition, but I’d just as well go shoot them by myself.

I hope you find more enjoyment in it then I ever did.
