LOL! Just wait a couple of days as they stage themselves for the trek at Grand Sierra. Then when it’s over, take a look at the rental RV lots and post burning man car wash, rv wash, school bus wash that they set up there. Maybe a de-lousing station would be appropriate as well. Pop corn and enjoy.
I’ve been warned that, since our Walmart is the closest one to BM, to stock up beforehand because there won’t be anything on the shelf for weeks...
