Going into the bike shed yesterday afternoon for the ride home, I discovered not one, but *two* flat tyres.
Caused, I think, by me mis-judging a ramp that leads to the bike shed, on the return from our lunchtime ride.
I crashed up a sharp kerb quite heavily.
So I had to fettle 2 flat tyres.
One tube from my seat pack, and one from my stash in my desk drawer.
Another from the stash went into back into the seat pack.
Bah!
