LOL. Both my boomer parents had beer procurers, boys with profuse natural fur. I have heard some of the PG-rated stories of how they raised funds, organized parties, and gratefully rewarded their hairy agents. This would have been long before carding. Body hair was the thicket...er, ticket.
Although the drinking age was 21, I had a credit account at the largest liquor store in my area and was accepted in bars at age 17.
In my neck of the woods, the ultimate score was a keg. “Kegger out at The Springs!! Harold came through again!” Word spread fast, and suddenly, out at The Springs, twenty or so teenagers in various states of summer attire, would gather. We’d swim, drink beer, play horseshoes, make out. talk, frisbee toss, etc. for hours. Sometimes the girls would bring sandwiches. It was a much simpler, and much happier, world, I can tell you!
