I rented from Provo, UT.
- know your density altitudes
- know your runway lengths (you'll need it)
- assume 4500 ft airport altitudes.
- Know your mountain flying and emergency procedures (also low clouds).
- recommend GPS (I didn't have one)
- Everything is rocky, few good roads; good luck on emergency landings.
- Go for the 172 over the piper at TO. You'll need all the climb you can get. i.e. kissin' rocks with your eyes :-O
- In the afternoon, turbulence is moderate to severe. Try at sunrise.
- Grand canyon has extreme min altitudes such as 10000 ft minimum altitudes in certain areas. That's 5000 ft above the rim.
