Wouldn't have been far off that Bob.
Track day the entire Winton front carpark was full, so given 60 on the track, dozen support vehicles inside... Rough stab would say 160-170 on the Sat (was cool seeing 5 Bayside Blue 34GTR's all parked next to each other).
The Show'n'Shine has 140 entered as there were 30 or so that turned up on the day, with another 20 or so on the street who's owners chose not to enter and 10 or so on trailers off to the side.
Was a pretty good turnout overall.
SAU Nats this year is also SAU's 10th B'day, so a few added surprises coming
If you can go to both, do that. If not, up to you to decide! SAU Nats has 3 solid days of stuff to checkout.
Thread is up in Nats section - 3 full days of action.
Website undergoing minor improvements based on heaps of feedback and should be done in a few weeks. Entry should follow a fortnight after with a bit of luck.
