I did geology way back when in university. Mostly computer stuff since, for better or worse. Geology kind of requires that you know how to drive... the last time I was behind a wheel, probably the summer of 1997, the geology van was rolling uncontrolled back down a hill as I tried to find the "stop" pedal. The other students did not before that point believe my claim that I did not know how to drive. Still don't.
