That was tongue-in-cheek on my part. I just love the government telling
me which direction I should walk in.

I sometimes use the altimeter in my Garmin 76CSx, but it's a
automatically GPS-calibrated barometric altimeter, and quite accurate.
Otherwise, I just look it up from several sources and get a rough consensus.

Orange triangle is the present standard according to:
http://www.parks.tas.gov.au/file.aspx?id=6789
Red is the nearest colour available from
http://topo.geofabrik.de/symbols_en.html
As they say, the symbol (if used) should approximate the one walkers
will see on the track, or be otherwise meaningful rather than just
looking nice.
