Stitchwiz, great story. When I few to live in the US for a while, a kid sitting next to me was carded, and I had to speak for him that he was of legal age, even though we'd met on the plane.
When we arrived at MacNamarra the first thing he did was ask a State Trooper if he could 'Bum a fag' (Borrow a cigarrette) and couldn't understand why the Trooper and I looked at each aother and burst into uncontrollable laughter.
I can understand about US beers - were far too light and tinny for my palate - there's a great one liner in one of the Tartan Terrors shows about American Beer.

My personal favourite, is the Belhaven Best as its very smooth drinking and goes down a treat on it's own or with a nice big lump of coo. It's light and hoppy, with a creamy after taste.
Hope your Dad enjoys his bevy.
