To be sure, the recent National Truck Driver Appreciation Week was filled with tributes to the men and women who spend their work lives and much more at the wheel of a truck. But, one stands out. This touching video by the folks who build Kenworth trucks features a cute little girl and her dad as they get supplies for and then build a treehouse. Featured, not surprisingly, are several Kenworth models, but also a woman truck driver. Take a look.
