Chris Lewis is to be praised, but he is not the only one (Keep the sea to your left: how one man and his dog are making their way round UK, 27 August). Many of us are following on Facebook the journey of hero Wayne Dixon, who is walking round the UK coastline with his dog Koda, cleaning up litter from beaches and roadsides as he goes and inspiring others to join him. Judging by his reports, he has encountered great kindness and hospitality from people he has met. He has been disheartened recently by the magnitude of the task, so deserves every bit of support he can get. Check him out under his name on Facebook.
