We leaving from San Diego to the Denver area soon. The most direct way is through Grand Jct. and I 70. Or. . I could go the southern route. . Flagstaff, Albuquerque and up I 25. This would avoid the "up the gut" route over the rockies, but add a few more hundred miles to the trip. I'm pulling a 10. 5K 5ver. What say you guys who travel these routes? Thanks for any advice.
