So I just checked around me. Heading towards the border, I measure 18" about 400' further up the mountain. Going the other way to the country club (about the same elevation as me but a mile further from the border and more exposed to the wind) I measured 12 or so. There's one helluva gradient in a very short distance...I'm really curious about what's up on the top of the mountain, but the road is nearly impassable at the moment.
