The Geeky Fab Five hit the road in an adventure of a lifetime. Packed into the camper of Lucy and Marina's grandfather, the girls' first stop is the Grand Canyon. Once at the national park, Lucy investigates erosion and rock formations; A.J. discovers a construction site on the canyon with a goal of preservation; Sofia is inspired by the beautiful jewelry of the local tribes; Marina watches the stars while Zara keeps watch for wild animals (not counting their snarky mascot Hubble the cat). There's plenty of fun and discoveries in the great outdoors!
