Advanced Open Water with over 60 dives, mostly in the Caribbean but also in Red Sea, Mindanao, Bali, and Atlantic coast of Florida. I do not know of any good diving in Indiana. France Park near Logansport, IN is the best training/practice site I know of in northern Indiana.
I have gone to Gilboa near Ottawa, OH several times. Cold, murky but well marked and a good place to do training dives. It also has a separate section for deep dives, but you have to clear it with the management before you can use it. They are strict about things there. Too many accidents with poorly trained divers.
PADI advanced open water....about 200 hours of underwater time....The large fish T Rav mentioned are probably paddle fish...they are common down there and used to be in France Park too....
