RE: [Philmont]: GPS

I'm afraid I was misunderstood. Yes, if you are taking lots of points
then it does take altitude into account. My example meant to say if the
only two points taken were at the tops of the peaks, it would be off by
more. I was assuming that the only points taken were when the crew had
reached camped. You know what happens when you assume though ;)
