High school. Friend's father owned an ambulance conversion company...we sneaked one of the ambulances one night and were driving up and down Woodward Ave. with the lights and siren going. We got stopped by police, for taking the vehicle, and for bottles of booze we had and taken to the police station. Our parents were called to the police station, five sets of parents. Somehow we were let go without charges..maybe the rich dad who owned the ambulance company had some influence.
