Scheels has all of your wild outdoor needs. Backpacking and Camping, Canoeing and Kayaking, Climbing and Rappelling, Diving and Sking, Fishing and Hunting, Hiking and Biking, Sking and Snowboarding.
They also have the clothing to match these sports. Need a new GPSr? I got my first one here and I'm still using it after 6 years of hard use. They also have maps of all kinds.
It's easy to find this place. Take Exit 240 off of Interstate 80. Turn South (straight, if you are coming from the West), and go a quarter mile to the north side of the Coral Ridge Mall. Coralville is located just NW of Iowa City, IA.
