We were delayed on the return leg of the journey home from our cycling holiday in Cornwall. I spent a happy hour browsing through the books in the children’s section of the public library. My favourite tome was a compilation of things to do when travelling along the M4 (specifically).

The suggestions ranged from singing well-known nursery rhymes (I particularly liked the illustrations of four and twenty blackbirds baked in a pie) to activities that were completely new to me. The best game involved guessing what the clouds might say to the hard shoulder crash barriers when it rains.
