The thought that springs to mind.
Full page ad. Open letter to the travelling public. Wouldn't need much editing in order to make it suitable for that forum. Not sure the costs of those sorts of things in papers around the nation. Now's probably not the time for it anyway but it would be at some stage.
I'm with you Keg, I had exactly the same thought. Open letter in the Australian, Age & SMH. And for what it's worth, I think that now is the perfect time for it!
