I'm thinking a two or three day camp trip. The trail crosses pavement in the middle so you could leave early at that point. It's a great historic 4x4 trail and one of the only main routes in the US that was not turned into a Highway. 140 miles of fun, 500 ft to 5200 ft elevations.

"a 3-day wilderness adventure during which you'll find no services, no stores, no motels nor perhaps a single other person"

It's also within a days drive of CO, UT, AZ, and NM. The 15 and 40 run right by it. A stock Montero with AT tires should be OK and least one 5 gallon jerry can.

Any takers?
