We just completed the Mt. Lemmon Tour and thoroughly enjoyed it including the music during breaks. In the springtime we did the Monument Valley Tour. Another excellent tour!!!
Loved this app! We found things we never would have found on our own. The Hawaiian music set the mood and the stories were interesting and fun! You should add the Iao State Monument though. We had trouble getting Google and Siri to get directions for it. And no fun stories for it either! Keep up the good work!
