Thanks. I first moved to Austin in 1982 and until September 1987, I lived in what were then known as Highwood Apartments at 9417 Great Hills Trail. There was another complex called Hamilton's Mark at 9617 Great Hills Trail and two other complexes between mine and Great Hills Trail & Loop 360. Back then, about the only other buildings on that stretch of Great Hills Trail between Loop 360 & 183 was Triumphant Love Lutheran Church and a small Jack Brown Cleaners.
The nearest grocery store/shopping center was the Balcones Woods Shopping Center. I used to shop at the Safeway there and I seem to remember there was also a McDonald's. I can't remember any of the other stores, though.
I remember once they started developing the Arboretum, they first carved out where the roads and drives would be but the area was still heavily wooded. I used to walk my dog there.
I moved from that neighborhood about the time they were getting ready to open the Simon David's.
