Parabellum, I am the last person to be critical of the volunteers and I have a working knowledge of the huge amount of work, paid and unpaid, to stage such an event.
What I'm saying is that I have very few expectations as a GA ppl holder of seeing much that is of anything other than entertainment value.
Frankly there does not seem to be any aviation related event in Australia that is targeted at GA, the closest being the SAAA show at Narromine, which I hope to attend again.
