Yeah, I think every large city has a ‘fag park,’ a park well-known (and published) in the queer community for hooking up for quick, anonymous sex. I know mine did. It was a joke to the teenagers, a place to avoid but which we knew existed.
Undercover cops were deployed to catch such propositioners in an attempt to suppress the problem. That practice is not allowed today. Too “homophobic” to insist people don’t have sex in public.
We have a few “scenic overlooks” off some main highways (either overlooking the mountains in western NJ or NYC from the cliffs on the NJ side of the Hudson River); they aren’t “rest stops” per se (no facilities), but they are like magnets for the freaks - probably more isolated/less monitored than full rest stops. As for the cities here, the regular parks are probably too dangerous at night; our deviants don’t tend to cluster in cities as they might in NYC or LA.
The highway cops will still arrest them for open sexual acts; I believe the city cops have “stood down” in any areas where they were meeting.
There’s a park in Washington, DC (I don’t recall its name) which was referred to as “Turkey Park.” Why? Because there’s a gobbler behind every bush.
