Walmart and other over night stays.

The reason I am asking this is because the town I want to visit I cannot find a RV park near by. Also I would like to keep the cost down. Here in Clovis, CA they used to allow over night stays, but some took advantage of it and was living in the Walmart lots. Some were eye sores with junk laying around on the ground. So the city passed a law not allowing over night stays. I have heard one guy tell me he came along one Walmart that didn't allow RVs in the parking lot. If I remember right it was in Nevada in a place of a lot of Casinos. It may have been Las Vegas. Buy that was years ago. I did find Walmart RV stay laws in California. Many towns do not allow stays. And here in California if there is money to be made you will get a ticket and have to go to a RV park (Clovis doesn't have one) for the night, so you will pay taxes. California may not allow prostitution, but the government they will prostitute themselves to make money.
