I don't know about MO either. I'm in Kansas.
Doing something like that (county installing dark fiber) would probably be regarded as borderline communism or some such! I won't hold out much hope for anything like that here.
Oops! Sorry.
The state lawmakers tried to keep the counties from getting the FCC money at first, but then the ISPs told them to stop since they were getting essentially free access to fiber and won't have to deal with the same regulatory hurdles as putting in the infrastructure themselves.
