Car accident - guy dumped his minivan over a hill, took out 2 gas mains, and then fled the scene, leaving a large quantity of blood inside and outside the car. We were mainly in a support role - stabalize the car on the hill, hose down the gas mains while they shut the gas off, and hose down the car to clear the blood off. Then we were on standby just in case the car caught fire or the tree it had hit would fall over. Took about 45 minutes. I didn't get to do a whole lot, but it was definitely exciting.
