So we're leaving in a few weeks for a trip out west, leaving from Kansas City. We only have 3-4 days to get to the Napa area in California, so it'll be some miles no matter how you go!! So far, the plan is I-70 west from KC to Denver, then up to Steamboat Springs, then 40 West to Salt Lake City, then either 80 or 50 through Reno, then to Napa!! I was trying to add a little scenery on the way, but with the tight schedule, would we be better just staying on 70 all the way to Utah, then cut up? Also will be staying in hotels at night, so any thoughts there would be great too!! Thanks!!!
