A Ice-Bat is a three 'wheeled' recumbent on skates that's propelled by a propeller. Totally weird, new and fun. Last Sunday was the first of two championship days. People competed for the fastest lap time and maximum speed. Both of them I just didn't make (I finished second, just like the day before). The preliminary results can be found on the Ice-Bat blog.
Thanks to Kim Alders, who I persuaded to try out one of these things, for filming me when I buzzed by.
