I wish they had a You Can Park list. that no parking list looks like every store in the US/
Trust me that listing is only a small part of the WallyFarts across the Country. And take note many of those are in and around the larger Cities, and in the Warmer seasonal States. Case in point I checked that listing against several of the Wallmarts in S.J and we'll not listed on there. Since the downturn of the economy and many people homeless more and more have turned to life on the road they are known by many names "Bare naked, Rootless" etc. or AKA Road gypsies.. This has become a big problem in the Southern States, and So-Cal.. Heck come Dec-April you won't be able to fit another motor home into Southern Florida. It's a new way of life and for many who are Living the Dream it works well for them. Many are actually Techies kind of working from Home but on the Go. Most of these are the larger motorhomes, but many doing it in a VW camper.
There are actually websites devoted to this couture and life on the move. And it's a growing community. Actually really not much different then the cross Country Truckers, and if it's fair for the goose, it's fair for the gander.
But in our case we'll merely passing though and won't be wearing out our welcome.
Trust, me. I've been on the road enough to know that it's really not going to be an issue for us to overnight in these locations. Don't forget that States also have Highway Rest stops, with nice accommodations, or the ever popular Free Petro's, Stuckies, 76, etc interstate Truck rest stops.
Some info here.. Plus a ton of info on the net.. yaygif
