If I might interrupt this discussion of the website's various conceptual frammistans, the bikes are about to run again. They'll start, as earlier, at about the 1 1/2. I haven't heard which one will run yet - will keep you up to date. (post)
Bike 1979, Al Lamb, is rolling. Through the three mile. Slowing at the 3 3/4. Fire and Ambulance rolling just in case. Bike is at the return road, thumbs up, rider and bike are okay.
Al reported big vibration, shut down just in case.
