I find their choice of lines/speed interesting .. full speed and virtually straight. Our little group did this for many years on Haleakala, but we carved full turns and kept speed in check. Even so, we'd sometimes eat it big time. I destroyed my ACL twice and had to retire until they came up with the Mountain Board rear disc brake system. From that point on, none of us ever wiped out. We also moved to night riding only. Cars can be seen from miles away.
