A $10 annual online contribution to the IGO buys you "Supporting Member" status in the organization. As an SM you'll get special benefits including an entry in our monthly "Prize Vault" drawing, advance notice of special events and promotions, SM recognition on your avatar or in an SM honor roll, and more. Most importantly, you get the warm, fuzzy feelings that come from supporting the organization that works so hard to further geocaching in Iowa! Please note, this in no way is considered dues. Membership in IGO is and has always been free.
