Proper soft weather to head out from Princetown on a quest. And, we found them all, all thirteen. The old packhorse track from Ashburton to Tavistock. The full set. Down, down, down, we trod over Long Ash Hill past Yellowmead and the Merrivale stones, right down to the last stone for a cuppa. Then up, up, up, past West Mead Quarry and its powder store, to explore the site of Red Cottages. To Hill 60 quarry and Hollow Tor, the prison bounds, North Hessary and back to the PoW.
