Bachelor party...

In just over a month my brother-in-law is getting married for the first time. He is 43 years old which makes this a momentous occasion in his life. We honestly never thought he would get married. Because he doesn't have a huge circle of friends in the immediate area it has fallen on me to plan a bachelor party for him. I have no idea what to do because the normal things like hitting bars and smoking cigars are out of the question. He is an avid fan of the outdoors but I have not idea how to plan a bachelor party with that sort of theme. I would love to have him say exactly what he would like me to plan but I know that he is not going to do that. I am just going to have to do the best I can and hope that the effort is good enough.
