It is not for me. Too many deviants. Particularly along the states that leave the interiors open which takes it beyond privacy into what i consider too weird. I don't even make a habit of those places at all. Osecola Florida had one along I think 85 for a while and the girls were actually decent about it with the Law constantly present inside the place. Good truck parking too. They actually leave you to sleep if that is what you are after.
The most negative contacts have been deviants in rest areas or those who are in states where pretty much nothing is legal. There is no class. I remember one black husband (Normally race means nothing at all until you bring in betrayal and dishonor to a marriage) advertised his wife as I was using a particular ridge across from his hotel during a active tornado warning area. Turned out the ruins behind me were the joint where they apparently made a living. I told them I am ashamed of both of them, who do they think they are? Take a 20 and go eat. Get out of my sight I need to roll in a short time to displace and reposition. And it wont be there.
To their credit they vanished. They probably drank it away for all I know.
People tell me sometimes something did not happen, they would absolutely reject it. However it is there and it did happen. Not on my end thankfully. There was nothing to be gained and everything to lose.
