Well outside the Metro area? Geeze, I don't know if I agree with that Dot.
Have you taken a drive out Campbelltown/Camden/Picton/ Menangle way of late? The Metro area doesn't knock it off until you get to the other side of Menangle Rd and it won't be long before that gets opened up & built on as well. More houses and residential developments have gone in and are going in out that way than you can poke a stick at. I was out in Camden on ANZAC Day and it looks nothing like it did even as recently as 10 years ago. Suburbia is spreading towards Menangle in double quick time.
In another 40 or 50 years they'll be right in the slot to pull another HP and sell the site off for development & move elsewhere. I just hope I am around to see it.
