Damn...what a fool. Fifteen feet isn't anything to sneeze at, even if the landing surface is loose sand or whatever. Nevermind taking your child along with you for the drop. Sheesh.
Apparently they jumped off a bridge into the water.
But it's still dumb. From that height you would hit the water pretty hard, and unless you know the area there could be submerged rocks or pilings.
Fifteen feet is like jumping off a fairly high diving board at a big public pool.
I suspect the depth of what they jumped into was a lot less deep than he thought.
Still stupid, he didn't know the depth, what could have been in the water regarding sharp objects.
I remember jumping off the 40 foot highdive at Lake Surprise in my youth. 15 feet would have been a snap.
