I like this so much. From io9.com:
The attraction, called "Professor Cline's Dinosaur Kingdom," imagines a lost chapter from Civil War history. It supposes that in 1863, a group of paleontologists inadvertently stumbled upon a valley of live dinosaurs. The discovery comes to the attention of the Union Army, who, recognizing the destructive power of the giant lizards, decide to capture them and unleash them on the Confederate Army. Naturally, it results in Jurassic Park-inspired carnage.
H/t to friend (and former student) Drea Nelson.
