This is one of my husband's favorite stores. They specialize in outdoor recreational equipment for camping, hiking, rock climbing, kayaking, and cycling.
You can join their co-op at a rate of $15 for a lifetime membership and earn dividends on your purchases which can be redeemed for merchandise or cash. The St. Louis location has a rock climbing wall. They offer a variety of clinics for a small fee or some times they are free. I like their shoe selection! :-)
