I got a call from the bike shop in Sacramento where Karla is getting fixed up. Frame is fine, wheels are fine (though probably will need some adjusting), hubs are probably fine. Just need a new front axle, a new left crank and pedal, and new brake levers. This shop, Bicycle Chef, offers a 10% discount to participants in the NorCal AIDS Challenge, so I feel fortunate about that too. Some of the parts have to be ordered and could take a couple weeks to arrive, but Karla is on her way to recovery. [Special thanks to the medical transport service...]
Meanwhile I discovered this today. Maybe my next truck will run on bananas, oatmeal, tofu, squash, broccoli, salmon, cupcakes, and the occasional cheeseburger and fries from In 'n Out (In fact this would be just the thing for a drive-thru). To name a few alternative energy sources. It even has an electric power assist motor to help out the carb motor out a bit.
