I know this is an older threat, but I have the same issue as the original poster (i.e. I'm a loud snorer). I'm preparing to begin sleeping in my car soon if necessary and am concerned about noise escaping because of having to crack the windows for ventilation. (I'd have no choice in winter here in the northeastern US, especially if I use a small propane heater or the like).
I'm in a small city with fairly rural areas minutes away. I've thought about asking to park regularly on someone's land/dirt road/driveway, in exchange for a small rent if necessary. But I would anticipate either:
A. If the landowner is someone I don't already know, they would be leery of such a person/request.
B. If I DO know the owner, they'd be overly concerned about my predicament leading to this request or they'd talk to my family who seem dead set against my resorting to this. (I have to do what's right for me, I know, and yet family approval is helpful if it can be maintained without great cost, if for no other reason than to avoid alienating them and their possible support in the future).
There is no BLM land to speak of on my side of the Mississippi River, just state parks that close at Dusk or charge per night to camp.
Thank you for all the info already shared in this thread - I've read it all. Would welcome any new thoughts.
Thanks!
P.S. In case it matters I'm a middle aged male and I imagine I would be comfortable in most parking environments, rural or urban.
