I feel like I hit a milestone of sorts yesterday. I apparently watch enough of all your videos, that yesterday when I was watching highlights from the Tour of the Alps, a bicycle race, definitely NOT diecast racing, and they briefly showed a graphic representing the race course, with all of its elevation gain and loss, my girlfriend walks past the TV and says, well THAT'S dumb. Cars will never roll down that.
Oh, my. You're absolutely right. LOL.
There's just something so soothing and calming about watching little cars roll down the track. Thanks for all the fun gang! That's it, end of story.
