I have yet to see a small one.
Ha! Good one, sjm.

Eyes, if you wouldn't mind saying, do you have a British connection? I've never seen anything like that Skidster. Where is the operator positioned?

The various images of "wagon" made me realize how important context is. If the reference is about cars, then people would know that wagon meant station wagon. My image came from my uncle's farm in Tennessee, when he would haul all kinds of things on the old wooden wagon, which I can barely remember being pulled by his mules, George and Henry. For most of my times there, though, he hitched it up to the tractor--a faded red Massey-Ferguson--and I'd catch a ride on it unless it was loaded with tobacco stalks, for which he would put the sides on it. But in my childhood, if I said I was going to ride my wagon down the hill, it was understood that I meant my Radio Flyer (hi, eta!)
