We can appreciate what you are trying to achieve here Les, but unfortunately I don't think there will be a mass turnout this year from us....
As you can gather we have previously attended in large groups the Mount gambier show but have experienced a number of issues..
Firstly as shane said a previous organiser (or similar) made us unwelcome as our cars were not deemed to be street machines (ie not old fords and holdens),
Also we have experienced poor treatment bordering on harrassment by the police because of our choice of vehicles. We are not hoons we are enthusiasts who would spend much money on the local economy... or NOT if we are targeted. Simple. We are currently working with police here in Adelaide to improve things and allow us to be enthusiasts instead of hoons as we are often labelled.
Thirdly, we are going to be attending EHP because they have released their dates first, are the only indoor show in Adelaide for us, and are showing us the support of specific categories for our vehicles and a special show'n'shine on the sunday for our members who don't enter the full show.
Perhaps you could look at addressing these for next year?... and yes we have plenty of members who would be interested in the driving style events.
