Pack. get on SSFrankenTrek. start to pedal down driveway. freewheelin' going forward. that's a problem! get off to find that i had mounted the rear wheel with the chain off the cog. brilliant. switched to the LHT shaking my head at the same time. i saw a thread recently about whether it was a good idea to have 2 bikes. case in point? tired, but it's Friday.
