We are planning to make a cross-country road trip from California to the East Coast sometime before the end of the year, most likely starting late October/early November. We have not determined exactly when we should start the trip yet. The route will also depend on the weather, but we would be willing to take the southern or northern route, or even zig-zaggy. We would hate to be rained or snowed on or weather-stranded during the trip. Does anyone who is a seasoned cross-country traveller or locals of the snowy northern states or Rocky Mountain States have any tidbits of wisdom to give me? Basically, I am looking for any areas and times of year to avoid when doing a cross-country. Thanks so much for your advice!
