A frequent question is where can go to find really dark skies?
If you live near St. Louis this is a real challenge. Most experienced observers use state or local parks and conservations areas. Here are some links and tips on how to find such locations. Once you find an area you like, identify the authority responsible, contact them and make sure you have approval. While most state facilities have sundown or after dark restrictions, most state park rangers are very understanding and even encouraging. Always be courteous and don't assume you have a right to be there without proper permission.
