Nice hikes, convenient, so-so grounds
First off, this park is extremely convenient to get to. So considering that convenience, the downsides may be a worthy trade-off ... it's still trees and trails and wonderful. For example, this site was an excellent meeting place for me and a friend coming from DC and Baltimore - right between us, and just off the highway.
Some very nice stretches of trails, and were empty as I saw them. Though they do cross over major roads.
Site host and ranger came by - and were very nice - though all things considered I like parks when you don't really see anyone.
Sites offer almost no seclusion or oneness with nature. I believe we got the most secluded site (site 16, and thank you to the other reviewer for the heads up) but still very exposed to neighbors and roads.
