Simple solution if you live in a van-- join a gym membership that has nation wide coverage (memberships are like $20 a month now). Don't shower in parking lots, that's just wrong on so many fronts. As far as people minding their own business, sorry I don't buy into that. We have to show Walmart that the RV community is willing to police themselves. Otherwise they will ban us from their lots. I use a Walmart parking lot about 3 times a year on our trips back east. I like our layovers there as it gives us a nice easy place to crash and reload supplies.
