Having a hot shower available on the playa is one of the ultimate luxuries; that's why I carry 100 gallons of water between my RV and extra tanks in a trailer. And I never seem to sleep alone, even if I arrive that way...
Too much is not enough, and when in doubt double it.
Point understood - why not shower around 4 or 5 p.m.? Water should be nice and warm from the sun. Of course there are those occasions when a cold shower IS a good thing. (LOL)
Do not think of me as gone, I am with you still in each new dawn.
