We'll leave SLC at around 4p.m. on 15th November, and don't need to be at Denver airport until 2p.m. on Friday 17th. So what route should we drive, and should we stay somewhere overnight or just get back to Denver late on Thursday? Mapquest suggests the northern route along I80, which sounds good as we are coming in around I70/I15 via Moab, but is that the nicest drive?
