Further endorsement for CAS in Arizona.
I was there in April/May last year for a month, and had a great time. Great team, very helpful and know their stuff.
Among other trips, I managed a Grand Canyon overflight and a transit over LAX whilst a Korean A380 departed a few thousand feet below me. Something never to forget. I don't think the A380 crew enjoyed being asked to look out for a Cherokee at 9000ft but I certainly did!
For anybody choosing to hour build in California; be VERY hot on your R/T. Busy airspace, and lots of VFR. Have to be on the ball.
