I volunteered my time at my friend's VW repair shop ~14hrs a day for a year for fun, and to learn from one of the local masters. We did both water and air cooled repair. He was my dad's age (late 50s) and had been open since the 1970s.
Now I'm inside nearly all day everyday in a university research lab trying to find out how/why certain types of breast cancer don't die when we treat them with drugs. Hopefully this summer I'll find a way to get one of my buses to where I live now so I can try for a monthly weekend vacation away from the city.
