I wouldn't know if my Dad drank more or less than a 5th because he has been buying his liquor in 1/2 gallon size for years. Once we went on a 5 day vacation with him. There were 6 adults and they drank 6 half gallons in about three days.....2 days were driving days....uggh!!!
Lucky hubby doesn't liquor anymore!
