I am leaving from Atlanta the day after Christmas and trying to get to Vancouver, BC in order to start grad school. I have allowed about 6-7 days to get there, but am not sure which route would be best considering the time of year. Is it realistic to try and go through Denver and SLC or should I try and take a southern route and go up the coast of California.

Either way it seems like I will hit mountains and snow at some point. I will also be driving a 12 ft. moving truck, so this needs to be taken into consideration as well. Any suggestions are much appreciated!
