I think there used to be, in times gone past, a lot of smmugler`s cave on the island, were they used to land illicit goods, Port Grenaugh, i think was one, i am not sure of how many others there are, were you could sneak in and out without being noticed, and also ( mates hiding you in the sleeper cab / bunk on a removal truck on the Ben ) which is not unusual, or certainly wasen`t in my day.
