Norton, how close to Billings will you be? There are some great rides around here. I have a few 20-25 mile rides I do, some flat, some with pretty steep hills. Then there are a variety of loops that one can do ranging from 28-80+ miles. Most have some good climbing in them. Just did the Beartooth pass again last Sunday and am about to post another ride report. It was SO BEAUTIFUL!!! Let me know. Maybe we can hook up if you're in the area.
