There are many groups state wide. I'm new to a couple in Kansas City, but I've heard of Lawrence, Manhatten, Witchita, Olathe groups etc.

This is the Kansas City group. You should be able to find other groups on meetup, and if not that, they admins of the KC group can most likely point you in the right direction.

There are important events coming up. You have less than 3 weeks to register Republican (feb 17th). Now is the time to get involved.
