Jimenez has some large abandoned buildings made out of adobe. I don't know if they were warehouses or factories or what but they made great boondocking spots. Parral is a beautiful town and the people are very friendly. The downtown shopping area is like a 1950s Main St. Both are worth seeing.
We need to get back to Chihuahua. The state and federal government spent quite a bit on infrastructure both in highways and the canyons. It is a must see for Mexico. Of course, I am the wrong person to answer this. I love all of Mexico. :)
