When I grew up in Britain, America seemed like an impossibly magical far-away place that you could only see on TV.
I suppose kids nowadays with cheap holidays in Florida don't feel the same, but to me, something as simple as a Dairy Queen is exotic and fascinating.
(While I'm sure that a British McDonalds Creme Egg McFlurry could - just! - hold it's own against an American Dairy Queen Reeses Peanut Butter Cup Blizzard, there's a glamour there still.
On my last trip to the US, my American colleagues were astounded at my reaction to a normal American School Bus.
