Share 'Nerdfighter Awareness'

It boggles my mind that this group only has four people. Four people.  The Minnesota group has well over 100 people. I just don't see how it can be possible that there are so few Nerdfighters in South Dakota, and so many in Minnesota. I really want to raise awareness for Nerdfighters. Not necessarily just in South Dakota, but everywhere. I just don't know how.  Do you have any ideas? :)
