I don't know that I'd call any town in SE Oklahoma gay friendly.

Not in your neck of the woods for a Talahina relocation but Ardmore in south central Oklahoma has held a Pride event for at least the last 2 years that I know of... May have been happening longer but just not as well promoted in years past.

I'm not gay so I don't follow the community too closely but the fact that I know there is enough support for the event makes me think progress is being made.
