I am planning to drive home to Pennsylvania from Idaho about two weeks before Christmas. I've made this trip several times before on I80 and I84. My concern is the weather in mid December. I'm traveling with my 2 year old in my small SUV towing a small uhaul trailer. I'm looking for any advice I can get as far as the best route, alternative routes if there is bad weather, should I stick with the tried and true or is there a better option that would be best no matter what the weather? I am not really on a time restriction, just want to be home before Christmas. I'd appreciate any advice. Thanks.
