A few years ago I was riding at the top of Shafer
Butte. It is a long ride, either by bike or by horse, and a great trail to
train for 100s -- horse, foot, or bike. It was a cool day and up near the
top Frank and I met a lone mountain biker. That biker stopped and we
talked for a while. The biker unwrapped a granola bar and offered it to my
horse Frank. Now, Frank actively looks for mountain bikers!
