I tried today for the first time.  I parked with "Geo1" .8 miles away
at about 282 degrees true.  The actual course length was about 2.5
miles round trip, and an elevation change of 300 feet each way.  Went
from prickly pear cactus in shortgrass prairie to Wild Rose bushes in
riverbottom deadwood piles.

I think I lost five pounds of sweat, but only a little blood.  I
dunno, I may try a different one tomorrow, since there are so many
around here.

No way to take sextant sights ... too much wind for an artificial
horizon. and I was following a ridge line west with a sharp drop off
to either side.   I could have used a theodolite and tables, maybe ...
but that setup is pretty awkward going down the coulies, and I slipped
on a gravel section at about a 100 percent grade.  I think resection
from known points might have worked if I cut down a tree or two for
visibility. Besides, I couldn't see the cache until I was about three
feet away.   (I took bearings from four places at about 100 feet to
get a closer idea as to where it should be.)

All in all, a GPS unit has a lot going for it in that game.
