Jumping 20 Feet, into nothing.

This summer, I went with my Ukranian Scouts Group to Algonquin park for the 49th anniversary. Point is, on the fifth day of the two-week camp, we went on a three day canoe trip away from our "base camp".
Where I'm going with all of this is the following; when we got to a first end of a lake, and were about to enter an interesting canal, we stopped for awhile to wait for the girls to catch up to our group.
There, we found a bridge [overlooking water] that we all jumped off of. Twenty feet. Into water, off a bridge. About one story high. Not bad, I think.
At first, when we jumped, we thought, "I'mgonnadie, I'mgonnadie! wahoo!!". I don't recommend jumping, but it is a once in a lifetime experience. I mean, I hope I do it again, and that I survive, but all the same.
For a final note, at the end, when we left, after the girls had already began their jumps, a guy and girl got chased out of the water by a snapping turtle, and we stopped.
