Amazing resource

I have never taken the time to review an app but this one was so incredible that I had to. If you are going to Yellowstone or Grand Tetons this is a must have. Very informative and interesting enough to hold the attention of my teenager. Worked perfectly. Helped guide me to the must sees in the park and some incredible things I would have missed if not for this app. Get it for sure. Couldnt recommend more highly.
