my husband and i are taking our 3 children (ages 7, 10 and 15) from maryland to breckenridge, co to visit my sister this summer. we're taking as much time as we can (unfortunately only about 2 1/2 weeks) to drive there and back with about a weeks stay in co in the middle. we've planned to take the first week to get there, driving through nashville, dallas, and santa fe, with 1 or 2 day stops to visit each and to break up the drive. we'll have a lot less time to get back (4 days max) and i'd like to take the northern route, but not sure what to see or how to break up the drive. i'd appreciate any suggestions, including places to stay, camp, and see along the way!
