It is marketed as the Home of Iowa's Best Thrills. Adventureland's history was conceived as early as 1970, when Des Moines businessman Jack Krantz had an idea to bring a Disneyland-style theme park to Iowa. He was inspired after taking his family to Anaheim, California years prior. The Des Moines homebuilder claimed that his inspiration came after spotting a large fiberglass pig on the side of the road near Manly, Iowa. His initial idea was for his children to sell snacks out of the pig-shaped stand during the summer, but the concept quickly expanded into something much grander. He ended up having a pig-shaped food stand added to the park, naming it Petunia.
