Which Gate should I go to for the watch party?

Hi guys, I am going to the watch party today but I am wondering which gate I should go to. Gate E would be closer to my seat but I checked the map and it seems to be the back gate. Will there be any celebration or activity at the front gates (Gate A/H) before the game? Also, it seems that they are going to give out t shirts for the first 15000 entrants, but with three gates open, howl are they anticipated to count the 15000? Any thought would be appreciated!
