I'd like to go over there (to the UK). I'd like to visit the filming locations of The Princess Bride. When she pushes Wesley down the hill, and he yells out "AASSS YOOUUUU WIIIISSSHHH!!!", that's Cave Dale in Castleton UK. Nice scenery in that movie, and it's one of our family favorites.
I'd also like to do some trout fishing in Scotland. My wife's cousin's husband lives over there (yet his wife doesn't..it's weird...Clemson grads).
