That canyon looks like big cottonwood in salt lake, what part of the valley you in?
Cool beans!, I'm out in cottonwood heights about a mile from the mouth of big cottonwood. I've been driving that canyon a lot lately and I recognized the inversion. How much does it suck to look for a white quad in the snow? Are you flying los?
