Unless you order gear, Sportsman's is the best place around here. As far a temperatures, it can get quite chilly during the mid to late season. I bought my waders at Sportsman's and love them. 1,600 gram Thinsulate. With those, thermals, and sweatpants, I stay toasty. As for the gate access key, the price for the first year is $35, and $25 each subsequent year that you turn it in to them. The conservancy office is in Belen behind the National Guard Armory. Easy to find. If you're coming from Abq., try hitting the river in Los Lunas on the west side, just next to the park. Head south, and there are a few turn-ins, off the levee road that lead you pretty close to the river. Only problem is that everyone else from Abq. likes that easy-access area, too, so you better hit it EARLY in the mornings if you want a decent spot. The hunters are usually pretty thick in there. Good luck!
