I usually just get "Welcome Home" as well, but once I had a friendly IO in Chicago who asked me why I'd been in the UK (holiday) and then asked, "Why would you fly all the way over there when there's so much to see here in the US?"
I said, "I've taken so many vacations to see things like a cattle drive in Dodge City, a house built with dinosaur bones, a dime Annie Oakley shot a hole through and the world's largest ball of twine. I think I've done enough Roadside America for a lifetime."
(Not that those things weren't interesting and I didn't learn a lot, but 1) as a child you can only visit so many museums before your head wants to explode and 2) you don't ever, ever, ever want to be in Dodge City, Kansas during August. Between the smells of the feedlots and the abbatoirs, it's not really fun.)
