CliffordK and fietsbob, good point about using their shopping carts. Maybe just a trailer, then. I should mention that I'm on near poverty wages, so *everything* is expensive to me.

CliffordK, of course you find trailers all the time; you live in busy Eugene, not tiny Arcata/Eureka. I did find this one, if I don't mind warped wheels. Thanks for the conversion tips.
