The problem with silos

Last century they built concrete silos all over the country along every railway line. Now they're a problem. They're too small, too inflexible, too dangerous to use, and too hard to demolish. The only use for them is to paint huge murals on them to attract tourists. Not really; many are still in use. But many are not.

There's an Australian Silo Art Trail (​www.australiansiloarttrail.com/siloart)

The photograph of the Weethalle Silo below is by Annette Green. Weethalle was the first art silo painted in New South Wales. The artist was ​Heesco Khosnaran.
