Southern Colorado Hwy 160 east to west

At 10,856' Wolf Creek pass is a serious climb and decent. Doable but you need to manually gear down so your engine does most of the braking. If you have to use your brakes more than 5 seconds every 30 seconds you need to slow down and use an even lower gear. Does your Ford toad have brakes on it? If not then I would have the DW drive it up and over and hook back up in Pagosa Springs. On the way down there is only one hard switchback that I believe is posted at 25 mph.
A easier option would be 160 to Alamosa, then 285 south to 17, and then in Chama, 84 back to 160. The train at Chama to the pass and back is an interesting trip #6..
