Bubbling

I tried a can of puncture repair stuff to try and keep myself on the road until I could get to the bike shop for a new tyre; I haven't used it before and got foam all over the place. This morning the tyre was flat again, but I pumped it up and after a bit of gurgling from multiple holes it seemed to hold, and got me to work. I had to leave a bit early for a medical appointment, and after about 10 minutes riding I heard a psssssst. By some miracle I was near to a bus stop where a fast-ish bus into town was due approximately 1 minute later, and even more amazingly I managed to scrape together the bus fare. After a bit of running at the other end I got to the clinic only a few minutes late...then had to wait half an hour, to be told that I should never have been invited for an appointment and to come back in a year. Sigh.
