That's fine Stu - the more the merrier for our display!
I'm not familiar with travelling from Erskine Park to Castle Hill, however, here is an idea of where we'll be and when:
Meeting point: McDonald’s Car Park Liverpool (near Harry’s Café de Wheels) @ 7.00am for 7.15am departure. Liverpool Mega Centre Cnr Cumberland Hwy & Viscount Place, Liverpool.
We can cruise up the Cumberland Highway to Old Windsor Road and Seven Hills Road onto Castle Towers.
I hope this helps and others see your post for other suggestions.
Thanks,
Ness
