There are two walmarts in Medford.
When I went through there 9 months ago, one allowed overnights and one did not. I dropped a friend off where she was going, and pulled into the one that allowed overnights. There was a class A there, and an SUV with blankets over the windows. It's not like it was a giant hobo camp.
I slept the night, and then moved 10 miles to an RV park the next day (in Phoenix, OR). That park was so lovely that I stayed 4 nights instead of my planned one :).
Point is, us occasional walmart sleepers ALSO drop money at local RV parks -- and more money if they are nice parks. It's not either/or.
And is this thread about the second Medford walmart no longer allowing sleepovers? Or is it about the one that hasn't allowed them for a while now?
