Opening day festival

Hey y'all! I'm going to my first ever home opener on the first of October! I'm really excited and I was wondering if there's any information out there about festivities before the game? I've searched around but I can't find anything. Ticketmaster says there's a festival before the game but has nothing else in the way of a time or what to expect. From what I saw last year there was a whole thing in a park and it looked like a great time. Does anyone know what I can expect?
