One way to find other Wiccans where you live is through the listings for individuals, groups, events and shops at The Witches' Voice. You can find the listings for Kansas at http://www.witchvox.com/vn/hm/usks.html
Another possibility is Meetup which you can find at http://www.meetup.com Then type in your zip code and Wicca to see if there are any local folks listed.
You might also talk to the nice folks at Heartland Spiritual Alliance who run the Heartland Pagan Festival every year near Kansas City. You can find them at http://www.kchsa.org/
