Not sure where to file this one, since it's more of a 'what the heck' than anything else.
My wife and I were heading out to fetch some food when we saw a car with a fire beneath it going down the road. I gave a honk and followed, the smoke grew black, and they pulled into a gas station. After a donation of water, the thing (newspaper bundle?) beneath the car was putout, but the car, now backed off the thing, had the engine compartment catch fire.
Long story short, the fire was put out with water and a fire extinguisher a few minutes later, the two guys were waiting for their friend, and we went on our way.
