Went to New Orleans this weekend. My wife was helping host an engagement party for a cousin at her 97 year old grandma's house. Her uncle and I were doing a little spruce-up landscaping in front of her house and he dug up a BARQ'S root beer(a local product which went nation wide when Coca-Cola bought them in the 80s?) bottle which has likely been buried for 30yrs. It has a 74 date code.
