What's the dumbest/craziest thing you've seen happen on Denver roads?

Saw a dude driving a truck around with a log bolted on to the front of his truck as a bumper the other day. I've seen people with their whole cars plastered in political bumper stickers, cars on fire, motorcycles taking up all the lanes, and more. It got me thinking, what is the craziest thing that's happened here? Nuclear transport spill? Airplane landing on I-25?
