We've hit a deer, responding L&S at full speed, totally creamed the brush guard, and tore the deer in half. Literally. Coming home from a late night call, I was asleep, heard the back up alarm then.. WHAM. We had the bay door folded around the back side of the ambulance. Pulled ahead, and the whole deal collapsed, throwing springs and pieces of gears all over the station.
Funny story, not an ambulance;
Back in the day, before half our town was turned into a parking lot; there was benches along the street. I was sitting there, talking to my barber. There was a garbage truck across the street. He pulled forward, got pinned on a stop sign, backed up, bent it over, pulled forward, bent it the other way. Backed up again, snapped it off at the ground, pulled forward, hit the curb, back up, blew one tire on what was left of the sign post. Backed up farther, off the curb, and... down onto the sign post, blowing another tire.
