I just found an FAQ buried on Wal-Mart's web site that talks about RV parking. This is great marketing. Here's an activity -- parking one's motor home -- that would drive most retailers and other business crazy. Wal-Mart, instead of patently prohibiting the activity, embraces it, knowing full well that they will pick up tremendous sales (and goodwill) by having people temporarily "live" at their doorstep. For all the annoying things that wal-Mart has become, they didn't become the largest company in the world by saying "no" to their customers.
