Frederick is locked down and has been for a long time.
The picture is Mid Atlantic Soaring Association (MASA) NE of Ski Liberty, so technically Fairfield PA.
The club fosters and promotes all phases of soaring training in the Mid-Atlantic Region, from beginning instruction, through advanced training, cross-country flight, and sanctioned competition.

At the far end of this taxiway is the road, going left-right. The cleared cut thru the trees is actually on the far side of the road and the only thing keeping drivers off the runway are a bunch of old tires that are visible in the distance.
Unfortunately it is also so close to Camp David the airspace gets shut with Temporary Flight Restrictions (TFR) every time a Prez stays at camp. Fortunately Trump didn't like the place ("too low class" he said) and Biden prefers to go the short distance to one of his two homes in Delaware.
It's the most UN-"controlled access" place imaginable with the runway T-ing off the county road. Fences? We don't want no steenkin' fences to catch long wings on.
Nice people to hang out with on a beautiful weekend day. A number of people keep campers behind the big hangar and stay the weekend.
