When I was a kid the outfield wall was a chain link fence. There was maybe 20 yards between the left field fence and the stands. when a homerun would come out there, the kids would jump out of the stands and there would always be this huge dog pile on top of the ball. later they put up a green fence and moved the stands right up behind it. Got you closer to bonds, but further from the good ol days.
You’ll also notice the huge area of foul territory. No Giant won the batting title while playing at The Stick. They figured you lose 30 or so at bats per year because of all that room.
