I did travel up to Thurso and found a couple of old empties three years after they all but disappeared.
Stranraer and up towards Troon was always a haven for old stuff, though I did have trouble in Stranraer from a guy called Norris McClean ( probably from the Clan McClean!)
Some old stuff kicking about but the coast isn't anything amazing. After you get up and past inverness your getting into a lot of old machines in all the little towns.
