Somehow, I have a hazy memory of seeing on TV a segment about a Haight Ashbury FREE MEDICAL CLINIC -- if I recall correctly, either the clinic itself is very famous, and/OR the founder(s) of the clinic are.
MAYBE it was the first of what later became low income "neighborhood clinics." It was located in Haight/Ashbury.
Frankly I wasn't paying much attention, as you can tell by reading my words; however, there probably are quite a few medical professionals still alive who volunteered their time there.
And Rose is simply so distinctive looking, that maybe one of them came into contact with her; MAYBE there is even an old medical file on her.
