That guy (GeoWizard) has an amazing video series where he attempts to cross the whole country of Wales while walking in a straight line [0], it is honestly one of the best things I've ever seen on the internet.
Thanks for that, enjoyable watch over a coffee. I'm currently looking into planning a kayak trip with some friends. Nice to see with a bit of imagination there is still some adventure to be had.
