FYI, the Bonne Terre website:
Bonne Terre Mine
Price is $65 a dive. Minimum 2 dives. I doubt anyone will be staying at their hotels. The hotel price is about $180/night. Its usually best to get there first before OW classes silt it up (or so I've heard...never been myself). The no knives/tanks/lights thing still pisses me off though.
When I was there, I stayed in the Super-8 motel....did a Priceline.com 'name your own price' for $38 (+ tax).
We were the only group there that day, no classes were present.
The light issue really wasn't an issue. On the first dive they didn't want anyone to use lights, as the lead guy and the backups used lights to communicate. However, they weren't too stringent on the 2nd and 3rd dive. One of the guys in our group was shooting video and used the light for the video quite a bit. I don't own a light , but then again, I never found myself wishing I had one on any of the dives.
