I think you're right Michelle, I think "Christmas Comes to Willow Creek" was not long after the Dukes went off the air, and the "Yellow Bird" was my most favorite part of the movie, even though Tom and John weren't bad either. Being a fan of the Dukes and having an older brother driving rigs, it was just one of those natural favorites for me. I still even remember how I spent my Friday nights back in those days, "Dukes of Hazzard" at 8 PM and "Knight Rider" at 9 PM!
also highway, it's neat that you brought that movie up, when I was younger I loved the Dukes of Hazzard and looked for other movies that John Schneider and/or Tom Wopat had been in. That was one of the first ones that they filmed (after the Dukes went off the air I think, might be wrong though lol). It's a heartwarming little movie, I still remember that the Semi was named "Yellow Bird" !
Of course another trucking movie (and short lived TV series) that I loved growing up was "The Highwayman". The truck was just too cool! It even transformed into a helicopter!
And if no one figured it out, that is where I got my handle from!
