Mine's bigger than yours! (Ladder Truck that is...), a photo by jitze on Flickr.
At a fire station just down the road from Google, Linkedin, and a bevy of other recent upstart companies, they had this rig parked in the forcourt.
It takes two people to steer it, the driver in the cab up front, and a wheelman on top bringing up the rear. It is the biggest ladder in these parts.
