This is a bit of old news, but it's still relevant. I just wonder how this happens? You see rocks, you're up high, you should use common sense. It had a happy ending, but it could have been much worse. It's a sad state of affairs that the Fire Chief is like, "Yes, this happens often. No big deal!" Really?
Read about it here, and use caution. The rocks can be tricky, and I'm sure they're very unforgiving!
