Traveling Colorado in November

technically, anytime after Sept 1, the highway patrol can implement the chain law. but its only for those going up and over the pass involved; you have plenty of warning and opportunity to get off the road before then. on your I70 route there is really only one short section to worry about, and only if an unusual storm hits right before you get there. early Nov your chances of sunny blue sky are much higher than your chances of snow. but in the Rockies we can see snow in July some years.
I normally don't leave my Co mountain home to go south, until Nov 1 and I never carry chains.

I need to carry chains, seriously? Never gave that a thought.
