Red travel guide with sun sticker

I lost my red paperback travel guide, 'Idaho on a Budget,' a 350-page Globe Printing edition. It's well-worn, with a sun sticker on the cover and a frayed spine, and I tucked a coffee-stained receipt between pages 128 and 129. I last saw it yesterday around 3:20 pm near the Idaho Falls Public Library on A Street, behind the main entrance by the bus stop. This book means a lot to me—it's full of notes from a trip with my grandmother, so I really need it back.
