It is on again, Campbelltown Steam and Machinery Museum's open days:

This year we expect at least a handful of Artist Blacksmith Assoc members doing their thang, as well as the regular narrow gauge train rides, parade of ex-military vehicles, tractors, stationary engines- steam and internal combustion.

See you there!
