Actually, I was not referring to the small white SOS mould on the wreck (http://www.geocities.com/marvintpaa/msos.jpg), but rather the 6' tall historical sign near the paved walkway towards the beach. I visited the Morrison around 100 times before seeing the sign for the first time just a couple of months ago, so I'd say it's not in the ideal location but I know it's there.
