Chaco canyon NP in NM ?'s

I have driven two 4WD pickups and a rental SUV into Chaco, but wouldn't take my car or fifth wheel on that road. On one of the pickup trips, I brought a tent, sleeping bag, food, and water and stayed at the park campground. The other trips, I have stayed in Bloomfield (closer than Farmington), and driven to Chaco from there. Once, I drove out late at night (after the Saturday night star party) and nearly hit a bull elk standing in the middle of the road just outside the park boundary.

FYI, the really bad portion of the road is on the Navajo Reservation. And they apparently don't plan to improve it in the near future.
