My boyfriend and I will be moving from Durham, NC to Breckenridge, CO at the end of October. It looks like the shortest route is I-70 across. We're wondering if we need to be concerned about winter conditions at that time of the year and if taking the more southerly I-40 for most of the route would be a better option. We're planning on 3 days of driving, would that be reasonable?

Thanks for any input.
