The cache is a plastic container with a logbook and objects.
Story:
Some centuries ago, Archibald Macphunn of Drip was caught stealing sheep, taken to Inveraray and hanged. His grieving widow came by boat to collect the corpse and on her way home, half way across Loch Fyne, saw her husband's body move. A nursing mother. Lady Macphunn hastily mixed some of her own milk with whisky and, cradling Archie's head, forced it between his pale cold lips. They twitched, his eyes opened and he breathed the words 'uisge beathe' - the water of life. By the time the boat landed at Creggans, Macphunn of Dripp was fully revived. Unable by law to be hung twice for the same crime, he lived to a ripe old age, albeit with his head listing to one side, and was know in Argyll and further afield as 'Half-hanged Archie' He now lies buried in Strachur churchyard."
Loch Fyne - Strachur Bay
We recommend you to walk so you can appreciate Loch Fyne and Strachur Bay on your right inside and Strachur House and Estate on your left inside. Great view of the house btw.
Good luck finding the cache.
