Anyone else ever try the Pantano Wash in Tucson? It's amazing (when it's dry). You can go for miles and the surface changes from sand, to gravel to pasture, etc. Some of the things that are great about it are scenery, driveabililty and how it winds through town at times. You can go from a completely rural scenery complete with high cliffs on both sides to a wide open wash cutting through Vail or Tucson.
