JustHecate I think that urge is quite common, apparently...DH got it when he went to the Grand Canyon & is not keen to go back in case it happens again.
I don't mind climbing mountains or doing slightly hairy scrambling, but only if there are no big drops nearby. I hate cliff tops & would not go to top of Eiffel Tower or CN Tower, for instance.
Oh and I HATE roller coasters. Just hate them so much. We went on a work outing to Alton Towers & it was wasted on me. I hated it.
