Seems a group of six kids decided to get high the old fashioned way: by climbing up there. The fact that they were all wearing swimsuits suggested I needed a telephoto lens for whatever was happening next, so I popped my bag and suited up the 7D with the Tokina AT-X 80-200mm f/2.8, then bumped the ISO to 1600 so I could shoot at f/9.
What happened next is that they each took a 35-foot jump into 40F water. It's roughly a tenth of a mile across the lake so after the first one went, it took about a half second between seeing the splash and hearing a very loud KER-FWUMP. The other five then followed in succession, although one of the guys clearly had some second thoughts for a couple minutes. Definitely worth the price of admission.
Until I got home and sorted my photos on a large monitor, I didn't realize I had enough resolution to catch an aftermath reaction: Yes, it probably DOES sting.
Wow! That's insane! Is there a known algorithm/formula that takes the avg height of a human, the distance from point x jumping down to point y into a brick wall (water) and surviving it? That seems a bit far of a jump to me, but I am no expert!
