Best route to Boulder Co. from Tacoma Wa.

I would like to see even 1 inspector on any road we are discussing when there is no snow on the ground, no snow predicted and it's 35+ degrees outside. I went across one of the highest passes in the US outside of Denver having out run a snow storm approaching from the East. I left Glenwood Springs, CO in a blizzard which had just hit. I figured I could travel faster than the storm and sure enough, by the time I got to Vail there was not a flake on the ground and I made a nice easy (but slow) passage without a single chain anywhere to be found on any vehicle. Oh yeah, you don't use chains on dry asphalt!
