...funny you should mention that, but we were thinking of getting some stickers made up for the interstaters as part of the process over coming months.
Thoughts were something based around "South of the Border" or "Going down South to get Dirty" or similar for the NSW/ACT/QLD Jeepers, something "Eastern" based for the SA/WA Jeepers, something "up there" for Tassy...and of course the NT guys could go South, East. or both!
Of course you can do what you like, but let us know if you'd be keen if we did it all centrally.
