The set used as the entryway for the home of Martin Kimbrough (Harry Townes) is the same used as that used as the entryway of Dr. Wallenberg's home in Fly, Little One (1970), (where Dana threatens to "fly away" from the second story landing near the beginning).
The cabin that Peggy and Toby are in was also used in Highway Patrol series " Fisherman's Luck" (season 2 episode 4).
