Yeah that would be macadamia castle at knockrow .. grass is always greener i guess .. im always wishing i lived in the G.T or anywhere else in victoria but i guess we have it pretty good up here in our own ways. See , all these things you find novel are just the same old crap for me , i grew up with composting toilets and mjdbrick houses etc so they do nothing for me .. be glad to pull over and take some pics of bananas and bamboo for you atomrat .. will be later in the week before im passing them in daylight hours though ..sorry op we have kinda sidetracked your thread , looks like busted bits off the old bridge to me but i could be wrong , depending on how far down the creek you were there is patches of it everywhere , never seen it upstream of old bridve though ..pebblecrete is my guess also
