MOO, a teen hangout spot like seems risky for anyone worried about being seen.
I my opinion, this location seems like a lot of nature/history hikes, you might not see someone for two hours, and then again see 6 or more people in half an hour. It seems regularly visited, not desolate.
However the parking area at the N300W entrance apparently was a problem according to owners who just closed it a few days ago (it was on their property,) "doing things at all hours" is what I think they said as their reason.
