I live in Denver. I definitley think planning a drive along I-70 around here (I haven’t gone too far East on 70) in January is taking a big risk. It very well may be 60 degrees and sunny. But the chances are very good there will be road closures, chain requirements, almost zero visibility, and other very hazardous conditions. Does your schedule allow you to check out the road conditions before leaving and plan an optimal time, or are you stuck to a specific date?
