If you've ever driven on I-95 through Delaware, you driven through the busiest fire district in the First State. It's the Christiana Fire Company, operaing 3 stations, 3 Rescue Engines, 2 Engines, 1 Ladder and 4 ambulances. The busiest rig on the roster -- in fact the entire state -- is a 2009 Seagrave Marauder, Rescue-Engine 126. (photos by Lou Angeli)
