Me and my dive buddy just made a trip to bonne terre mo. in jan to dive the bonne terre mine. it is a old lead mine that is really cool dive with alot of history. it was featured on discovery channels weird america and was voted in the top 10 adventures to take by national geographic. i would highly reccomend that you google this and see for yourself. it is a little pricey but the diving is worth it and the staff are very nice. i know that we are planning to go back and do more diving there in the summer. hope to see some of you there.
