I think we started going in the early 80s. Post Borg, but Mac, Jimmy, Lendl, Becker, Evert, Marina, etc. I remember watching Stefen Edberg as a teenager playing the junior tournament on the of the side courts, thinking, ‘wow, this kid is good!’
Nothing like going the first week and being able to hop around to different matches and seeing the crowd gather as word spread about an unexpectedly tight match.
