What it was like
The argument does not start at the stadium. It starts at a family dinner, or in a group chat, or in the front seat of a car where one person is wearing red and the other refuses to acknowledge it. Nowhere else in baseball is a rivalry this domestic — the two fan bases usually know each other personally, which is precisely what makes it unbearable.
Chavez Ravine handles it well. The San Gabriels sit behind the outfield, the light goes gold about an hour before first pitch, and 56,000 people from Koreatown and East LA and the Valley and every city that ever exported a fan end up talking to strangers, which almost never happens here.
Gates open two hours early and that is not a throwaway detail: batting practice in a quiet park is a different sport. Dodger Dogs have been a matter of public dispute since 1962. The third-base pavilion gets loud first.
Bring the person you argue with about this. They are the event.
