I witnessed that ride, crazy. The motorcycle club I belong to promtotes that hillclimb annually and has for the past 90 years, yup thats right 90 years. The hill is privately owned and is only ridden on once per year, while many would like to attempt it, it is located on private ground and is watched over pretty closely to ensure there is an even playing field for all competitors.
This coming weekend is the famous Widowmaker hillclimb in Croydon UT, should be an outstanding event.
