YUK. that is sure nasty.
driving home from a horse ride my friend and I (pulling our monster 4 horse trailer) slammed into a plastic kiddie pool with a metal ladder attached.
it flew off the truck in the oncoming lane, our eyeballs got seriously wide seeing this thing fly off and literally right in front of us, we had absolutely no choice but to hit it. luckily nothing happened but we discingrated that sucker :) we figured the horses wondered what the heck we hit with the noise of it all.
insane things happen.
