Given the current recession and the lack of any major new iron on display
Interesting that you say that as it counters what I have been told by the various manufacturers.
Anaheim generally has one of the larger static displays because of the saturation of helicopters on the west coast of the USA and its a good market for manufacturers.
For an Aussie going to Heli Expo its also the cheapest option as Qantas, Air NZ etc fly SYD, BNE, MEL direct to LAX so its easy to get there.
Hope that helps.
