If I was 20 again, instead of "That crash was cool" I forsee an emergency room visit now. If you get one let me know, I want to sit on the river bank in my lawn chair drinking beer. I can be your rescue crew, I'll bring my fishing pole and put a bunch or treble hooks on it to fish you out.
You know those "jet packs" attached to the water skis? Saw this the other day, someone is always thinking. In Dubai they have a lot of low bridges over open water like the Chesapeake Bay Bridge. They are using them for firefighting when an accident occurs.
