The society will mark the milestone on February 17.

Secretary Andrea Cross said wristbands for the event were now available to pick up from the office at the Horsham Showgrounds.

She said the office would be open on Tuesdays and Wednesdays from now until the celebrations.

“We’ve had a few calls from people wanting wristbands already – we’ve probably had about 40 people interested so far, and that’s not including members or sponsors,” she said.

Mrs Cross said preparations were going well for the celebrations, which would include live music and pizza.

“The rain has been fantastic because it’s greened the area up,” she said.

Mrs Cross said the celebrations would also include a display of old agricultural items.

“So if anyone has old ploughs or anything like that, let us know,” she said.

The celebration will be at the Horsham Showgrounds from 5.30pm.
