It's 2.8 miles from little five points to grant park. I'd say that's relatively close.
I was at the old home from 1954 until 1964, and was never at the Briarcliff
facility. I probably left about the time you guys were arriving. I also had three siblings there with me. Several of us post messages here glad you found the site. I'll check out your post card on facebook. It's probably the same one I have.
Good hearing from you!! Take care.
