frank,
It's not far from you at all.......Barry gave you simple directions. Look on a Map for Rt501 , the Camp Mack Scout camp is only a couple miles north of the 322/501 intersection.
The shoot is a lot of fun and just an informal deal with nice terrain and a lot of varied shots.
You should come on down.....we might even be able to snag you a free hot dog or hamburger from the Big Buck Hilton.
I'll be there the whole weekend, as will Frank S. and we can hook up and shoot some together.
Try to come very early and register if you only have one day, that will give you the chance to shoot most of the courses.
We stay in the lodge at the end of the parking area to the right of the sight in / practice range.
