Superior Producer is the best wreck out there. It's a little scary when the large cruise ships are in, but well worth it. Sometimes the water is a emerald green color on the way down, but it will clear up once you hit the wreck. Watch out where you park your car as local hooligans might try to break in. A good solution is to have someone drop you off and arrange a pickup after the dive. Make sure to check out the artifacts left over in the hull of the ship, there is a purse and a shirt down there for sure. The best secret is the air pocket in a cargo hold on the side of the ship. Nothing is stranger than breathing air under 100 feet of water! (Great spot for a quick romantic moment, as well.) =)
