GPS and skiing experiment

Hi,

I have made a simple experiment. Just bought my TomTom One GPS and took
it to mountains in Breckenridge, CO. Enabled recording software and pace
started skiing down at moderate pace on Peak 7 blues.

here are two parts (google fails to load everything at once - too many
way points?):

I would never tell that at certain parts I was doing 44MPH.

Also map indicates I was in the forest - not sure if it is GPS error or
the satellite imagery mapping issue.

BTW, as far as the altitude, my GPS was about 30 feet off when comparing
with blue informational sign showing the altitude at certain point of
the lift. BTW, google earth is showing a slightly different elevation
then my GPS and those signs too.

Cheers, Andy
