It's always worth stopping to investigate anything that seems out of place. In this case, it was a red sandstone block integrated into a grey stone wall which I passed in Drymen on my way up to Loch Lomond yesterday. It turned out to be an old mile stone, with 22 carved on one side and 12 on the the other. These are the distances to Stirling and Dumbarton, respectively, as shown on the mid-19th century map on the left (where it is marked as M.S.).
