"The milling thousands laugh and play!"
I think those 4 women stayed friends for years--certainly, they visited every once in awhile, because I remember this picnic, and that Marjorie Albright brought chocolate covered donuts ☺. (I think she's second from the left in the lower half of the photo below...and I think that link HAS to be her).
Actually, I'm hoping that someone will google "Marjorie Albright" and see the photos. Maybe well be able to figure out who all three were for sure. I think the woman next to mom at the picnic was Flora...?

Marion emailed to say she remembered Flora's last name, and that sparked a memory for me. I think the four women were:
MARJORIE ALBRIGHT, FLORA HAUSER, MARIE KLINKERT AND (mom) LINDA JANSON.
