I was driven down the #10 from Bridgewater to Middleton and drove by a large concentration of granite boulders along the highway in Shannon Lake ( between Dalhousie Crossing and Squirreltown ). If anybody finds themselves out there, have a look-see in the woods and report back.
Also Granite Village along the south shore past Port Mouton, but before Shelburn may have some potential too.
