Just when you think you've seen it all, along comes a different combination of circumstances.
On the way home tonight I felt my back tyre going soft, so I pulled over and put it on the pavement for a look and it was immediately obvious where the problem was - a big chunk of glass was too much for the armadildos.
So, turned the bike over next to the railings on a wide bit of pavement on Millbank and started fixing it (stupidly, as I'd been away at the weekend my decent pump was still in the pannier, so I was going to have to pump it up with the teeny carbon jobbie!).
Hey, where's the nasty accident coming from you ask.
Well, as I was beavering away I very fortunately glanced up to see a lady with dark glasses and a white stick heading straight for the front end of the bike. I ran over to her "excuse me" I said, "oh, sorry" she said "I was in a dream and wasn't looking where I was going".
Just imagine the paperwork if I hadn't spotted her in time.
