I don`t drink much beer , but

Growing up in Colorado we bought 6 per cent Beer at Liquor Stores and Bars. 3.2 Beer was sold at 3.2 Bars. Only groceries were bought in Grocery stores.You could buy 3.2 at 18 but 6.0 had to be 21. Imagine my shock moving to Arizona and seeing beer and Liquor in Grocery Stores and Pharmacies( 4.2) and no stand alone Liquor Stores to be found. I've been gone from Colorado for 8 years now so don't know current laws.
