Bakery on wheels

Do you remember being excited when you would hear the familiar song of the ice cream truck as a child? Maybe even now you get that hint of excitement from the sight of the brightly colored, traveling ice cream truck.  Now, picture this--a bakery on wheels!  I can't imagine it would be very difficult.  I mean, you would definitely have to bake all of the products outside of the truck, but I think selling them city to city would be a great idea.  Who knows, maybe some bakeries actually have trucks like this!  Would you buy baked goods from a truck?
