Ranger Rob is a young ranger-in-training who ziplines, swings and even snowboards his way around Big Sky Park, the coolest natural adventure park ever. It features all sorts of ecosystems and Rob thinks of it as his very own adventure-filled playground. With so much to explore and discover he's in for the experience of a lifetime--and you're invited to come along for the ride! Ranger ready to get outside?

Today, Ranger Rob celebrates Earth Day with his friends in Big Sky Park and many wonderful activities are planned (think windsurfing in Frosty Fields or driving a solar-powered car through the desert). But first, Ranger Rob has a mission to accomplish: deliver new rain barrels to the jungle restaurant!
