...but they NEVER appear in the good ol' overly repressed USA any longer. I am fascinated by the subject and the idea and potential possibilities of public GH's.
As for myself I can only think of perhaps 3 or 4 times maximum since about 1985 that I have ever seen an active looking, not otherwise boarded up one in the USA, and the last one I ever saw to date was nearly 15 years ago in Tennessee (and I used that one to receive a quick and pretty decent BJ BTW...)
That would be the ONLY time I ever used a public GH. Although I wished I could have used the others I saw previously, but there were prevailing circumstances that kept me from doing so, even though I sure as hell fantasized about it a lot after I left.
Almost 100% of the time they are VERY short-lived things in the USA.
