I recently came across the YouTube channel of Knight Rider Historians. As their name suggests, they research all aspects of Knight Rider, and now own a couple of screen-used cars, and are in the process of restoring the screen-used FLAG semi (truck and trailer). I've only just started watching the videos because most are in the 30-60 minute range, but the one below caught my eye. It mainly concerns the episode 'Out of the Woods' (previous mentioned in this thread), and discusses the Duke Farm and Boar's Nest filming locations.
