Best Yellowstone Resource!

Best investment if you’ll be visiting Yellowstone. As others have said, this app doesn’t rely on cell or data service so it *will* work in cell-starved Yellowstone. The narratives were well timed, very informative, and witty. It also pointed out a couple of dirt road side trips we would’ve missed had it not been for the app. Everyone in the car, including the kids, enjoyed it immensely. Awesome app!
