I've had good experience with Sportmans warehouse as well. Much better than Cabelas or any other chain in my opinion. Geared more to actual hunters and their staff is pretty knowledgeable.
Idaho Archery is a great Proshop near the Fair Grounds, and in Caldwell/Nampa area, Archery Central is another great spot. Both locations have great ranges, as well as quality techs that live and breath archery.
