I remember when Eric Estrada (or the other guy??) had an accident filming one of the episodes which ended these two actually riding bikes (they used stunt doubles and a trailer when they filmed close ups). One of the episodes beginning scenes was filmed near my (parents') house in Northridge, California back in '79 or '80 when I was 9 or ten (the one, if you remember, when the mayor's limousine was stolen, and Jon and Ponch happened to see it abandoned next to the road--that episode :)).
