The neatest place I worked at was the DOT test crash lab in Auburn Hills. I was there to install anounciators to warn people that atest was taking place. Anyway to see a bus go down the line at 60 MPH and hit a four foot thick wall was amazing. When I was there they tested the bus and a few trucks - I thought what a waste until I saw Chrysler test crash vehicles, they did it in groups of 5.
