Thanks to everyone for the ideas and inspiration for "Stretch." Everything came together very well on the back, especially my old license plates. I like that even better, I think, than the requisite skateboard deck. Add the studded tires (see "home made DIY studded tyres" in the Winter Cycling forum), and it's perfect for the skiff of snow we got last night. I see a lot of miles on this in days ahead. Thanks again.
