You must be young. As a youngster, ignorance is bliss. As you age, you find out that you need to learn some history, so maybe it won't repeat itself.
MareenLouie was a top A/Open player when I met her, went on to win a couple of WTA events in the early 80's.
Her sister, Marisa, hit the ball faster than any person I'd seen, male or female, and I was playing Open Men's tourneys the following year. Head case, of course.
Dana was Brad's younger sister. She called Brad a pusher, as she liked to hit hard.
Susan was the #1 rated A/Open NorCal in 1979.
