Farthest west, so far, was Yellowstone and the farthest south was 2016 Rally, so , looking forward to Co. Will be a 3 day ride for me.
Looks like their are a lot of Nation Forests NW of Denver, still early but looks like my routes are 80 out of Des Moines, heading west, or 90 to around Sturgis and then head south and run threw some of that forest area, down to Cortez ? 80 would be my best bet to catch some riders for company...
