Well, that's a major downer. Was scheduled to go out with the local Bromptonauts for a tour of the city's obelisks, went to top up the tyres, discovered the back wheel had a puncture. In a mad rush, because of course I had left checking too late, I took it apart, fixed the hole with a quick patch, pumped it up and discovered I had failed to fix the hole.
So, excursion abandoned, and I am peeved at myself for waiting till the last minute to prepare.
