Rockridge Farm, Marietta, GA

Does anyone here remember Rockridge Farm in Marietta,GA? My memories are from the 1960s, but I didn’t know the place well, just spending a wonderful day at a hunter show there when I was a kid.
I have a new friend who lived just the other side of Bells Ferry Road, sometime in the 1970s, not a horse person, and I don’t know if Rockridge was still around in the '70s, after the horrible fire there.
Anyway, this friend and I are wondering where exactly Rockridge was, and if any of y’all remember it. It’s more than just another horse farm that has disappeared, it’s a good memory (if a dim one to me).

I’ll duplicate this on the H/J forum.
