ONe day it was hot and windy, and I hadn't shaved that day, and I got that salt residue all on my face too. I also get it on my gloves. Pretty cool.
I just soak all my stuff in a bucket, and then drink that water the next day as my electrolite drink. It saves me money on gatorade costs.
(Remeber Dune? Didn't they have some kind of desert suit that let them recycle all their bodily fluids?)
