Four friends and I will be taking a road trip in the beginning of January from a suburb above NYC to San Diego, CA because we are moving for a year or so. Each of us are driving our cars out there and would like to take our time. Since one of my friends drives a 1991 Le Baron we want to take our time to make sure all the cars make it: about 6-7 days.
Does anyone have tips on this winter-time road trip? What highways would be best to travel at that time? Is it too cold to camp out in Texas/New Mexico/Arizona? Any cool things to see along the way?
