Fort Lewis College in Durango of course. I attended Northern Arizona in Flagstaff and there are a bunch of great trails right outside of town plus Sedona is just right down the road!
I had a pair of 780mm on my bike when I was riding in AZ and UT, but I ended up cutting them down to about 740mm when I came out to texas because the trails are a little more crowded out here with the dense vegetation.
