Today I went to Tavistock to buy a new hat. The Pannier market waterproof clothing stall had nothing waterproof in my size. The farm supply shop, ditto. The hiking shop had a £25 folding waterproof hat that fit, but that I didn't like. Devon Hatters was closed.
I really would have thought that if there was one item you could reliably buy in a town on the edge of Dartmoor with astonishingly high average rainfall, it would be a waterproof hat. I think Tavistock is still in 'late summer' mode...
