I decided to take the copter tour because I have never been in a civilian copter. My wife does not like any small aircraft, so this was my first chance. Several things struck me:
1. No smell of hydraulic fluid 2. Padded seats 3. No sudden drops or lifts because of thermals 4. Music in the ear phones ("Flight of the Valkyries" on the way in and "Theme from Top Gun" on the way out).
This set show the initial views going into the canyon.
