After seeing the kayker going over the waterfall, I remembered that my nephew competed in a downhill mountain bike race at Tish Tang and found this video showing how challenging the course is... Which got me thinking about mountain bike crashes.
I started watching crash videos at other locations... I think this one sums up that famous Wide World of Sports clip, "The Agony of Defeat" and condenses it into 4 seconds.

(Listen to the thud... Watch it over a few times to get the full effect )
Clips like that make me not want to load the mountain bike up and try that Tish Tang course...
