For a while now, I've been looking at the Stratford-upon-Avon canal and all of the gaps along it, with an idea that you should be able to walk from Stratford to Birmingham and cache all the way. The numbers won't follow in any sensible order, as the gaps will come and go. This one is filling a recently opened up gap.
