My wife and I were on a Model T Tour in Colorado-Wyoming in late June a few years ago and we had to go over trail-ridge which is the highest continuous road in the United States. While I was having a little trouble with the carburetor and getting into the steepest part of the climb and no guard rail. My wife was becoming a little nervous to say the least it began to snow as neared the top and my windshield di not have a good seal. So while struggling to keep it going, listening to my wife and snow hitting me in the face while driving it was just a great experience. When all said and son was a great trip but you will never get me near Trail Ridge again in a Model T.
