Telescope Reviews: SE Missouri dark-sky sites?

I live in the metro St Louis area. I normally drive about 40 minutes and observe from a yellow area (as I have just discovered the Google/light map thing) but I can drive about two hours south-west and reach into the light-gray areas in SE Missouri. These would be the areas around Coldwater or Centerville.

If there's anywhere particularly nice to go I'd like to hear about it. I normally just pull off a country road wherever I feel like it so I don't need to have a specific place. There are sites listed on that light pollution map that have no info, so I don't know what those are--if that's any kind of a public observing area, or if it's just somebody reporting from their own backyard who lives there.

I thought of Taum Sauk (because of the elevation) but I don't know if it's closed at night (unless you camp, which I don't know I want to pay for a campsite) and it is not as dark anyway--it's in the green/violet region. All the other fairly-high areas also seem to be green or violet levels too.

Most of Sam A Baker state park is good too, and it may have higher-altitude access,,, but I dunno if you can be in there all night... :|
