Used to be a guy around here that had an early '60s fire truck. It got used a lot for high school senior pictures, wedding parties, limo service, bar hopping and rabble rousing in general. Lights and sirens worked and he had fitted the area normally used for hose storage with bench seats and cooler.... You get the idea. I never had the opportunity to ride/party on it but he stayed pretty busy driving people around through the warm months.
