Thank you once again to everyone who posted. I have now returned and literally had the time of my life! I only managed 30 hours but like as been mentioned already it was extremely hot, topping 42-43*c on several days.
Sweat would be pouring from me over the city anytime I was below 4000ft and even at 10-11,000ft over the mountains it was still around 12*c
I would highly recommend anyone to experience flying in the USA if they haven't already done so. It's nothing like back home. Airspace and charts are lot more easier to interpret, almost all the controllers I spoke to were friendly and helpful and the weather was perfect on all but the last day! I'd also highly recommend Chandler Air Service who are a great bunch of people and very laid back. We rented an RV for the 2 weeks from Cruise America and were able to pitch up just outside the airfield fence in a car park. Got a chance to drive to Vegas and the Hoover Dam in it as well as plenty of trips to Wal-Mart! Ended up flying to the Grand Canyon itself (although avoided the airspace restrictions).
....And managed to bug out 40 minutes in their Pitts S-2C...What a machine! By far the most amazing flying I have ever done and so far the best machine i've ever flown in (other than the 747 that took us over the pond of course
)
