Yes, Mrs./Dr. Morgan/Mountain was quite a lady. There is even a bust of her in Warm Springs, GA, I think, at the polio hall of fame, or whatever they call it, where she is the only woman out of 16 honorees. I well remember those days in 3rd or 4th grade in Pasadena, CA. They used to give us shots, but then one day it was a sugar cube....

PS--I don't remember them changing needles every time, but then I probably was looking the other direction :)
