This app was well-worth the money spent!!! We (parents, teenager & preteen) recently traveled by rental car through the Tetons and Yellowstone and luckily had this app loaded and ready. We had studied a couple of travel books and had a fairly good idea (or so we thought!) of what to see, but this great guy, (the voice on the app, we decided to call "Mr. Guy, Sir") amazingly rode along with us, pointed out great sights, advised us what not to miss, and educated us on history, geology, animals, and so much more!! (The kids even enjoyed learning all that!) Our trip was a bucket list item, and this app made it better than we imagined possible!! Thank you, Mr. Guy,sir, all 4 of us thoroughly enjoyed traveling with you!!
