In 1988, while camping with friends in Algonquin Park, we buried a bottle of 12 year old Adams Antique. 40 oz's, unopened. We've dug it up twice since (via memory and a map), each time not opening it and put it back. Its been at least 10 years since the last 'digging'.
This summer, we're getting back together to find it one more time.....this time to crack it open and enjoy it. Like an old friend, can't wait to see it again.
