I think I have found my next (first) reason to travel to St. Louis. So I can get to the Bonne Terre Mine. The Bonne Terre Mine is an old mine that has flooded and can now be dove. It is open year round with the air temperature in the mine being 62 degrees and the water temp 58.

The Mines have lots of various "trails" to swim along with lots of things to see from natural cave formations to equipment left behind in the mine. And if you don't have a cavern certification, they will help you get that also. Well worth checking out.
