Cool report, that's beautiful country. I grew up in New Mexico and really miss the desert. Ain't no desert in Virginia or anywhere close
Knowing the desert, I learned to stay out of "dry" washes if there was even a remote chance of precipitation. I saw some phenomenal flash floods come up in NM in a matter of minutes and under a blue sky. One day my brother rode his bike off a six foot drop-off into a wash that had been stone dry when we'd ridden there the day before and eroded out like hell the next day. Weren't you a little concerned about camping in the wash?
Anyway, hope you were packing some heat given all the BP and illegals traffic in that area. I'm more skeert of crazed humans than I am of sand and mud
. Hope your leg feels better!
