Morris dancing is so much fun. I can definitely recommend it if you can get to try.

Yes, there's a community of people who live on the canals in narrowboats, who are called 'continuous cruisers' because they have no fixed mooring, and they move from place to place every two weeks. With a good arial you can still get internet so a lot of them work remote jobs. It's a very off-grid lifestyle, and fortunately there are no waves on the canals (except when another boat goes past,) so I think you'd be okay :)
