The Best Laid Plans...

It’s a really warm day today, again - 26°C and very little wind. So, despite my cold I decided a swim in the lake was just what I needed.
The water is so warm that you don’t feel even slightly cold as you go in, and the rocks are warmed by the afternoon sun.  I’d have a swim and then lie on the rocks, reading my book and relaxing.
The plan went well until I’d just got to the “reading the book" part (see extra). Then an ominous rumbling announced the arrival of a thunder storm in the distance. It wasn’t heading for the swimming place but it soon closed of the sun and I decided to take the book home.
I filled in two more gaps today with backblips. The 14th (ice-cream anniversary) and the 17th (wild pig sign).
