I've had fun at pretty much every match I've ever shot, I bring the fun with me.
But for favorites if I had to name them....
For a 'travel' match, I'd have to say Winter Range. Land Run would be up there as well.
For something closer to home, I'd say the Shootout At Pawnee Station. I enjoy it so much I pull my camper out a week early and help set up, and stay and day late to help clean up. Permanent props, lots of stage dressings that come out for the annual, great scenarios, lots of dry camping, wonderful people, and a ton of fun.
