What?

I had a good morning sorting out which clarinet mouthpiece works best on my Uebel.

Then later cycling through the woods was fun, and I saw a lot of things to take photos of. I was puzzled by these large snakes, or pipes, until I got closer. Then I saw that they seem to be some sort of sandbags, but I couldn't work out what they were being used for.

This evening the CFS decided to make itself known again, this time with feeling a bit cold and achey. Ah well, these things happen. I think it's the change of weather causing the problems. Maybe we'll get sunshine tomorrow and all will be well.
