No kaboom to report. Just going down to the basement and seeing the front tire on the Bianchi, my primary commuter, flat. It was fine when I parked a few days ago. Oh boy, another task but at least it is bicycle-related.

On our tandem ride yesterday we were eating lunch at Fern's, spoke briefly with a few other cyclists there, very gregarious. They walked around the porch out of sight as another bike rode up. A few minutes later we heard the gregarious guy say "You are about to have a blowout there", followed by something equivalent to "Yikes!" The newcomer had taken a cut to the sidewall of his rear tire, hadn't noticed it. He seemed to have it under control a few minutes later, putting a filler in the tire.
