I meet a lot of folks, both online and in person, who rave about the fact that they can camp in WalMart parking lots for free. We also have a number of friends who tell me they use WalMarts to save campground fees. Things sometimes get heated when I suggest they should stay at a campground rather than try to save $30. I hear/read lots of rationale about how they spend that $30 in the WalMart store, so they're not trying to save money; That they're only staying to get a few hours sleep before moving on; That WalMart encourages them to stay there; How they're really safe because WalMart security comes and checks on them frequently; etc. They really get mad when I explain that WalMart hires the security folks to protect the stores, not the folks who camp in their parking lots. They also don't like it when I suggest that extending the slideouts, putting out the fake grass, deckchairs, barbeque and satellite dish doesn't sound like a brief stay for a nap. It's true that WalMart's policy is to allow RVers to stay overnight in their parking lots, although the final decision is up to the individual store manager.
