DUB -> LHR -> YOW

Actually home, but that's what I just finished. Dublin's rental car return signage is perhaps some of the worst I've ever experienced, and to make it even more confusing, you don't return the car to where you pick it up -- so you can't even trace back to where you started. And, of course, you're following this poor signage through roundabouts on the wrong side of the road.
