eubSnow practice trip, 14 April:
Me looking squinty.
Navigation practice trip, 17 March:
I thought we'd get away without "the full Heybrook Ridge experience", i.e. rain, but we did not. I was l33t -- in final following a bearing most of a mile quartering steeply downhill through clearcut strips, landed five paces to the right of the target. Partner for some practice, Gary, was a Boeing engineer -- we each noticed that the other did /60 conversion to radians to do small-angle trig (tan x = x), commented (on the advice to take lots of bearings as the errors cancel) that independent errors sum as square root. When anything was set on the ground near the stump practice area, hundreds of tiny black bugs materialized on it.
