While I have nothing against the Tailem Bend profect it will never be a great success as it is percieved as too far away. Yes I know it is really no further than Mallala ut from what i gather will never be a racetrack as such, just a venue for sprints etc.
All the more reason to support the Tailem Bend project, which will host both bikes as well as cars (remember how good the combined car/bike days were at Mallala?).
AIR for all its faults, real and imagined can provide for a Far greater cross section of motorsport. Though Tailem will still be a extra venue that should still be of great use to the motorsport community.
