Walmart and other over night stays.

I have been reading peoples post about stopping over night at WalMart and other free places and Camp Grounds. I have not traveled in a RV for many years and when I did here in California there wasn't many places to stop for the night. Many cities have passed laws banning stopping in their towns. Rest stops are closed and those that are open are full of truckers. I remember traveling up I-5 north of Sacramento pulling into 4 different rest stops and finding the RV spaces filled with 18 wheeler. Finally I pulled into a truckers space sense they were in the RV spots. The Woodall I bought was very miss leading on what you would fine. One place they rated it as average. I wouldn't let my dog stay there. The power plug in was on the ground and had been ran over many times. The rest room and showers were non-useable. Why pay to stay in a dump. The town in Kentucky (Russeville) has no RV parks near by. WalMart is the only place to stay. I haven't found out yet if the WalMart there allows over night stays. I would hate to get there and have no place to stay.
