Everything CM said and then some. Like getting up at 3AM to drive 2 or 3 hours and be setup an hour before sunup, the cold weather, big winds( we sunk our boat once with 4 of us in it.....another story), always buying the latest gadgets, never seeing your family four months at a time,...gas...gas...gas, and a dozen other things I can think of all in the name of fun. The best part though is the comradery with your hunting partners and the end results of a well planned hunt!!
.......correct me if I am wrong.
