Great idea for using Location technology on your phone. It even pre-warned you things like "if you want to visit this attraction, the turn is just ahead in the left". The topics covered were interesting, but there could've been many more since the drive is several hours and there were some long periods of silence ( I didn't want to play music during the silence since the tour voice could start speaking any time). Also I think there may have been a "more info" section for each area but the voice only prompted me once to listen to the "hear more". I was driving alone so having those play automatically would be better than me having to click on while driving.
