The local 24-hour Super WM has a large lot, bordered on two sides by a city river park; actually a very nice place. They use to allow overnighting. But it was abused, with the same 5-6 rundown units there continuously for months. I don't know it for a fact, but very strongly suspect that's why it's now signed for no overnight parking for RV's and trucks. Dam' shame.
