Bob,
I'm glad that the dust did not deter you from coming to SnF.

It's a great show, and some years (like last year) it rained hard two days before the opening. Not much dust at all where I was camped. I think you'll like it a great deal. RV's just keep arriving all week, the trade show floor has all the aviation vendors, and the hands-on workshops run continuously. Oh, I forgot the airshow every day, is usually worth watchng at least one day during your stay. I also love the Factory demo fly-by's at 11:00am each day.
I have never had a difficult time with the arrival procecure, but I usually arrive late in the day, or very early in the am. At those times, I've had anywhere from 0-3 aircraft in front of me, pretty easy to deal with. Memorize the approach instructions, so you can keep your head out of the cockpit, pay attention to the radio call outs from the tower, and keep your head on a swivel. You'll do just fine. I've never had any airborne "close calls" in 7 years of arriving.
