Built up a bike and did not set rear derailleur before rushing out to test. Put the chain right off the top and into the spokes and broke a couple. Painful lesson.
Was riding alone, ran into an older friend and joined the Slow Spoke group he rides with. Figured it would let me catch up and be a change of pace. Guys up to 80 with some that swerved and struggled. Well, I was the one that was not paying attention and toppled at the light, they felt bad for me .
