[leibnitz]

I am in Mongo Valley. I have just accepted the Lefty Lugnutz bounty. This basically involves learning a sleg call and what not. I talked to the ex-hunter who has sent me to kill a sleg and in return he will help me learn the call. The only problem is I cannot leave the town! People in the town keep saying to follow the river out of town past the waterfall. Huh? I eventually checked walkthroughs for the game which said I need to walk to the port authority desk with my pass in hand and he will open the door for me. However, there is no one at the desk. I do have the pass. Anyone have this problem or know what to do?
