Oregon State Parks
When I was a full timer, I worked graveyard shifts. The State parks in Oregon say NO OVERNIGHT PARKING. They Don't say anything about daycamping. So I would go to work at night, and then camp at the state park in the day.
When I registered my motorhome in Oregon they charged by the foot. I asked why it was so high, and the Oregon DMV told me that all of the money from RV registration goes to State Parks. So I didn't feal bad about boondocking at the State Parks.
