I have seen guys in private boats up there bring a carton of cigarettes or some handfulls of gear like hoochies or coyotes to bribe the guides at the fishcleaning station for info. It worked really good, a couple packs of smokes got this one guy a list of waypoints and a tour through the guide's bin in his boat where he stowed his gear he was using. It's alot cheaper than going out with one for a day to learn the fishery.
