[Christ]

I've been keeping a few "Scrap" bikes around for basically this sort of thing... never know when the wheels, axles, etc might come in handy for something, like a yard cart.
I don't really ride much, but I would if I had a motorized vehicle... I'm still looking into building a reverse trike moped-dealy. If I do that, I'll put a lynch-hitch on the back of it and also build a small trailer with two wheels to pull behind it.

I had also thought about a single wheeled trailer, but that brings up stability issues when improperly loaded, or objects moving, etc... I'd rather take the penalty for the extra tire all the time, than take the penalty for wiping out at 40 MPH just one time.
