A few years back we visited Summer Lake wildlife refuge in S E Oregon. Almost adjacent is a small store and roadside rest area.
For one reason or another the water was turned off at the rest area and toilets closed. The store was closed due to water shortage.
In the rest area I was surprised to see a late fifties man and family washing playa dust off their Sprinter based camper.
When I asked about his water access he explained how clever he was to bring a outside faucet key, hoses etc., so he can wash the dust off his Sprinter each year as they return to Seattle from Burning Man.
Steal a precious resource after playing in the desert.
