Quite a few years back I built up a HardRock as an all-purpose commuter, hauler, beater. It lived for a few years under a tarp in my backyard, which was an interesting experiment in rust. It fulfilled its intent, but it was heavy with a deadened (as opposed to lively) ride. I eventually lent it permanently to a local friend whose commuter had been stolen, and last I heard it had been stolen, too.
