The next day was brighter and warmer, with more swimmers. The Maud Foster Windmill was open for visitors on Wednesdays, so we got the tandem out and cycled back in to Boston. The mill itself was interesting, and I was amazed to discover that it was self-financing – mostly funded by selling the flour they grind. We had a quick lunch back on board and then set off. With some miles to cover in the coming days, anything under about ten miles each day would be added on to the requirement for the following day. In contrast to the days travelling in the opposite direction, the weather was warm and bright. Even though we were pushing in to a slight current, and so taking longer to cover the miles, I was enjoying the gentle cruise.
