Campers recreate and explore the Mesozoic eras through diorama building and strategic-game playing. They construct dioramas representing the environments in which the fierce predators of the Triassic, Jurassic, and Cretaceous periods ruled. They are used in tabletop gaming, as well as to examine how these gigantic killers lived, thrived, and vanished. Visits to Smithsonian museums and the National Zoo help tell the exciting story.
