To perhaps further explain how this works, if you have a safe place that you are willing to let a fellow traveler park in for a night or several, you register with https://www.boondockerswelcome.com/
Your address is NOT posted.
If you are needing a place to park while you travel, you look for hosts in the area you will be in and contact them and ask permission.
When a person(s) who are traveling through your area contact you and ask permission to stay with you, their profile is available for you to view to make sure they are decent people. This profile of theirs also has comments about them from other people they have stayed with.
You can then email them back and give them your address, phone # etc. Whatever you provide them with is strictly between you and them.
There is a yearly fee for this service, but It is less than what one night at a rv resort would cost you. If you host and get 3 good feedbacks, the next years membership is free.
The world is full of friends that you have yet to meet.
