Cache is near a crossroads and there are several places where you can pulloff and park on the roadside.Just don’t block any driveways. There is not alot of traffic on these roads, but be quick about it so you don’t attract attention from muggles.
Powdermill Run is a creek that runs into White Oak Run just south of here. It is the cleanest stream in the whole area and nearby is The Powdermill Nature Reserve where much research occurs. You can park at the Visitor’s Center and walk 0.4 miles along the road to this cache if you want, and enjoy the quiet woods.
Cache is a Green Nano, so hopefully you have good eyes
