Probably about 10 years ago or so I was up there at night trying to capture some video and just see what I could see, and the police showed up because the adjacent houses seen my headlights and called them. Yes unfortunately there have been a lot of beer and other kind of parties up there, grave stones kicked over and some actually removed. One year a long time ago me and a friend went up there just to walk the path to the water shed, and when we got to the main entrance and parked we seen a bunch of idiots must have had an all night binger up there because several graves had garbage, beer bottles, cigarette packs and other disgusting things I won't mention littered all over them. We went to what was then called Riverside where we worked, and bought a bunch of trash bags, gloves and a pooper scooper and spent the rest of the day cleaning up the mess. I remember someone came up and thought we made the mess and yelled at us for it. We had to explain to him why we were there and what we were doing instead. What really pissed us off is that we noticed the graves that were littered were people that were police or in the military. So I really can't blame people for calling the cops when they see headlights going up there at night time.
