I agree with GB being hit or miss. Especially with guns. Bow season is ok, but it's not so great with firearms. Too many people and too many ways to access the place. I will say this, the place is always loaded with hikers and bikers and people with dogs. There's trails all through the place, so don't be surprised to get in a stand and look up and see someone walking their dog 50 yards away.

As far as SM, it's a big piece (long at least). Not sure about the 70 parking,and whether it's legal or not, but there's access points along the Appalachian Trial on 40 on the Washington county/Fredneck County line. There's a parking area there. There's also an access point outside of Smithsburg that also has a parking area. There's also some public land along the AT outside of Boonsboro off Reno Monument Road. The land is skinny, but long. Get a map because it can get hairy as to whats' public and what's private. I don't think Reno Monument gets as pounded as 40 and Smithsburg.
