I would think that the rules have changed since I was over there. The duck hunters earn more money for Paul (Burbank) then the goose hunters. That is because you can get 300 dollars per hunter and you can pack 12 hunters in a group and you can run two groups a day. Geese you only get one set of hunters per day.
So your comments make sense. Sounds like he needs more land to hunt the geese so the duck hunters do not impact the goose hunters.
