"One of the main causes of the fall of the Roman Empire was that, lacking zero, they had no way to indicate successful termination of their C programs."
- Robert Firth
Taking the "Journey behind the falls". A highly overrated experience IMHO (somewhat more interesting in summer time than winter though), but instead the point of heading down is to go to the lower observation deck where you get to see the fall close-up from down at just above river level.
