A few years ago, we decided to travel to Wales, mainly to visit the Doctor Who Experience, but also to pay Llanfairpwll­gwyngyllgogery­chwyrndrobwll­llantysilio­gogogoch a visit (for the novelty factor). We flew to Stansted and then drove through the English countryside and had a truly magical moment, when we decided to stop for a short rest. In small town we drove onto a parking lot, and then followed the sign to a small park/picnic are. The park was right at one of the waterways and there lay a few of those narrowboats and one or two were navigating the channel. It was such an unexpected sight, it felt light out of this world. Before that I had never heard of them.

Later I saw a depiction of life on such a boat when my wife watched Call the Midwife. It must have been Episode S05E07.
