That is for sure. I took several waypoints while I was at PTC last week,
(Ponil, Pueblito, T-Rex, PTC Dining Hall, etc.). I recorded a waypoint at
the Urraca trailhead, turned off my GPS to do something before going on the
trail, turned it back on in the exact same spot I recorded the waypoint and
it said I was 140 feet from the trailhead. I use a Garmin Etrex, and it
usually isn't that bad, but it does illustrate how far it can deviate from
actual points.

I was planning to compare my waypoints to those published on the lists that
Seldon has on his webpage. I haven't gotten to it yet, though.
