I've always been attracted to the eastern side of England - it's what comes of always having lived in the western half. So high on the list is the Fosdyke and River Witham down to Boston (and of course Black Sluice the and"Navigable Drains" - how could anyone resist black sluices and navigable drains?!). While I'm over that way it would seem sensible to take in the Chesterfield Canal as well even though this will mean spending time on the tidal River Trent.
Now I have taken a boat down the Trent. I've even steered successfully into Keadby Lock. But I'm still a bit uneasy about it and with visions of falling off the back and watching Starcross sail off into the distance as I go down for the third time (I never learned to swim) I think I'll have to recruit some experienced crew for that part of the trip.
