You're right, Nature's paint-can is beyond our best tagging skills. Indeed it was an excuse to risk a careless step, a bad moment, a just-about-to-be-broken beam, leading to a horrible fall, various injuries, no immediate death, but lots of suffering, including broken bones, open wounds, and once the water takes you possible hypothermia and drowning. Yes, we are still stupid kids (for being in our late 30's)! But sometimes and itch just needs to be scratched.
