Most memorable case I attended was a Trauma job, much like what BM described.
Bike VS Car 4 km out of town. Bike was in excess of 120km/h when hitting the car doing a good 100km/h.
Bike had 2 on board. 1 with an open face helmet. (Rider and passenger located 200m down the road from the bike).
Some nasty injuries, some open fractures, spinal injuries, and some serious, serious skin graphs required. (Resulted in retrieval funnily enough).
Normally the calls to the Hotel when you deal with inebriated persons are always quite amusing, whilst the most difficult at the same time.
