Below are places that I have safely stayed overnight and recommend to other road travelers.
Another safe option that I utilize is Harvest Hosts. Their platform offers access to wineries, breweries, museums, and farms that allow you to safely park overnight. This membership costs $80/year and they do ask that you make a purchase while visiting a harvest host. This is not the most affordable option, but it is a great way to support small, local businesses and also get a safe place to sleep for the night. In addition, a lot of these locations may be super helpful in places that don't have any free overnight camping nearby. Harvest Host has saved the day multiple times for me. Below is a map of their locations.
