Driving back from CostCo yesterday morning, and my youngest son says, "There's a rust bucket truck behind us". It was in the right lane, I was in the left. I moved over to prepare for a turn up ahead, and the person driving went to the other lane. It had a really ratty paint job that could be on purpose. License plate said "RUST BUC"
I'll try and get a pic, next time I see it.
Pic copied from Post #41 and cropped to show the one it looked like.
