A dizzying view but looks worth the scary walk, at least while the fence is still there. There are certain angles when it's impossible to keep the horizon straight and vertical lines vertical. So I usually go for the screwy tilt. :D
Good idea - I've done that in quite a few pictures too. I was thinking of your cafe picture as we were wandering through York in the snow today. Wandering, and wondering if I could find anything as chic for JDP: I didn't, not this time, anyway.
