Newerdays you do not find Boars anymore inside of this 3 parted fence. The south, center and north part.
Which is anyway broken at some spots, so the yellow Papoo who are now swarming this place are even outside of it.
Here are young to old.
The Area is reachable with 2 Teleporter. The first is this , The Boar Field low & medium TP. in the northwest corner of the south part.
The other one is the Boar Field High Tp. which is located in the middle of the northern part.
Nearby in its south you can find the Race Track and if you head even more west you can enter Crystal Center.
At the oposite side to the east you can find Papoo Village TP
