When I lived in KC I played on a kickball team that Wacky eventually refed for, but before his new$money joined it. I played with friends to begin with, but I def made new ones from that. So 8MP is on point.
There is a pretty active KC young professionals group in KC that is good. I know the person who started it, I can give you her info if you want.
We are buds lib, no matter what interactions good/bad we have on this blog.
