Before you leave for the playa, do your future-self a favor and pack a “go bag” of clean clothes for the slog home. I keep mine in the front seat of the car during the event. After everything has been torn down and packed away, before I step off the playa and into the car, I drop trou and change every item I’m wearing. The bag contains blissfully clean stuff that hasn’t been tossed around my tent with the dirty bits. It’s the only way to go for the long ride home: clean undies, dust-free sunglasses, unscathed flip-flops, a hat to hide my scary hair. Clean shorts and a T-shirt feel restrictive and straight but when I stop at a diner along I-80 I’m glad for the armor. You’ll still look crazy-dirty to the outside world — might as well not bring the funk too.
If you are flying home from Burning Man this advice is more of a mandate. Kisses!
