RE: High altitude ???
Sportrider,
You need to go down to your local supermarket and ask them to let you stand in their walk-in freezer for 1/2 hour.
Immediately after that time reconsider this idea to move to Colorado.
You seem to be a desert rat - Colorado has snow, a lot of it!
I'm up in the low mountains of Northern California trying to fugure out how to get back to the Imperial or Coachella Valleys.
Just my opinions, we're all different.
Good Luck,
