I have to admit, now that it's a bit chilly, that I do miss my windshield. And as far as fatigue goes, it really helps with that when you are running at highway speeds. There are times on windy days that I feel like my arms might get popped out of socket at the shoulder. The good Lord knows that with my bulk, I trap plenty of wind on my own.
