It seems there was a massive pile-up on Interstate 94 near Kalamazoo, Michigan, today, involving over 100 vehicles. One of them was carrying fireworks - and it caught fire. Here's raw video of the result.
I've been on many roads and covered many miles, but I never considered encountering a burning fireworks truck! Apparently the authorities forgot about fighting the fire and just concentrated on getting everyone a safe distance away. Good call, I'd say!
