 So cruise in for some fun and celebrate all inspiring, nostalgic Americana cars every Tuesday, April through October. Over the river and through the voyage to grandmother's house to see a coaster that's new for the entire crew and they call it Good Gravy. Good Gravy, the new family roller coaster at Holiday World and Splashin' Safari. Twist and turn past a gigantic rolling pin, milk bottle, and more in a race to save Thanksgiving dinner.
