Calling CASA!
I hate to have to say it, but.....
If CASA wants to do something to change the negative perceptions that surround it in the GA world, it has just been handed a golden opportunity....
Step in right now and become the major sponsor for Ozkosh and save the event.
Whatever it costs, it is a small part of your marketing communications budget and in terms of bang for buck you will never have a better opportunity to effectively change industry perceptions.
