When I was young I use to ride my motorcycle on solid ice to school before I got a car, a 1972 Yamaha DT-2 250 Enduro. My riding buddy had a 1975 Suzuki TS- 185 Enduro. We lived on those bikes year around and rode in all kinds of adverse weather.
Today I don't trust my balance or reaction time enough to try that. Add to the fact my bones are not as forgiving as a young man's.
