E412 had just returned to the station from a gas leak call and was dispatched for an MVC with a pick-up truck into a building.  S414 and E413 arrived to find a pick-up truck that had glanced off the side of the old ski shop building and come to rest beside it.  One patient had self extricated and a second needed help getting out of the vehicle. Crew from 41 and medics from station 56 and 50 worked with the patients in packaging and patient care.
