Yeesh!
I was just checking my email at ATT/Yahoo and they have an article up on Yahoo news of an 18 year old young man who was standing on a rock trying to take a selfie of himself against a waterfall at Yosemite National Park and he fell 820 feet to his death.
They make it sound like he was standing on a wobbly rock near Nevada Falls.
I guess it happened mid-week. He was on an extended vacation before going into the Israeli military.
