The old Cruiser doesn’t like high elevations. We had to stop frequently along I-70 heading west from Denver. Here’s a few photos along the road and from our stop at the rest area in Vail Pass which is at 10,600 feet.
BTW, if you look closely you can see wild Big Horn Sheep on the rock wall near the road in one of the photos. We saw quite a few of these critters along I-70.
