It wasn't big enough to be a separate political unit. It looks like the county eventually added street names and numbers, so people have normal addresses now. I left in the early 90s, before that happened.

I did see the same process happen in rural Wisconsin in the late 90s. I had an address by then, but I had a friend who lived out of town and had no address initially, but they went through and assigned one to everyone. I think the stated reason was to help emergency services, but of course it helped a lot of other stuff too.
