When I lived in Colorado Springs 6000ft + altitude, the lower humidity did a great job in moderating the temps (never felt quite so hot or cold).
I'm fairly warm blooded, Ill ride the bike to work (35minutes)it it's above 35. Hopefully at above 35, I wont have many frozen spots.
My tolerance for heat is less, can get to 100 here, We'll see how I do this summer with the heat on the Busa.
