1 other mistake in Roadside Courtesy - chronological order
Starring: Harriet Hilliard, Ricky Nelson, David Nelson, Ozzie Nelson
Ozzie and the Bridge Group - S6-E34
Continuity mistake: Ozzie goes to a boxing match. Stock footage shows two boxers fighting in a ring surrounded on all sides by ten rows of seats. Almost every seat is occupied. The close-ups show Ozzie sitting in the front row and there are only three rows of seats behind him.
Trivia: In the later seasons, almost every scene taking place at the Dobson and Kelly law office or in the Emporium or other local business is preceded by the same clip of a downtown street showing "First Bank" and a passing bus.
