I would be physically unable to call another human being “Mountain Girl” without making a hash of the thing and being thrown out of the room for harshing everyone’s groovy groove. Nor would I be able to substitute MG, knowing as I do what it stands for.
“Mountain Girl, would you pass the salt, please?”
No. I could not do that.
Mountain Girl had Kesey’s baby, then Garcia’s kid. She wins being a Hippie Chick.
