My mother and I are moving to Boulder, CO from Bloomington, IN but we're first stopping in Nashville, TN to see my sister for Christmas. We're planning on leaving Nashville on the 26th. The general gameplan is to just get to Boulder in one piece without too much hassle from weather conditions and traffic. We'll be driving a Uhaul with a car dolly.
I'm looking for the best tips to get there. I've been experimenting with google maps and the fastest route, according to google, is Nashville -> St. Louis -> Kansas City/I-70 -> Denver. Nonstop its calculating to be about 24 hours. We plan on stopping at least once every 5-6 hours to stretch/etc and at least 1 overnight somewhere.
Alternatively we could take I-40, which seems to me the safer bet as far as avoiding weather.
Advise on a more detailed route would be appreciated.
