Hot Springs and Hot Messes in Yellowstone & Idaho

In Yellowstone, the hot springs smell like bison, and the bison smell like farts. Old Faithful puts on a show, and we stumble upon a chipmunk paradise by a waterfall. Over in Idaho, the paw-ssenger princesses get their first-ever Pup Cups (even the cat!), and we chow down on "Idaho Nachos." Buckle up and prepare to get locked inside the RV with us...no really!
