This 1968 Cadillac ambulance, re-purposed in what appears to be a camouflaged stunt double for a similar vehicle featured in the movie Ghostbusters, was parked at the Montgomery County, Maryland fairgrounds during the Foundation for Amateur Radio's hamfest in Gaithersburg, Maryland on September 9, 1984. The vehicle later moved to the tailgate area. The seller was referred to as "Johan" but I don't recall if the vehicle had call letter license plates (front license plate is blocked with something that looks like a parachute pack but may have been a generator) so I don't know if it belonged to an amateur radio operator or not. Anyone know who "Johan" was? Did anyone encounter this vehicle at other Maryland area hamfests during this time period?
