Hello,
There are great dives all over Lake Michigan and the Great Lakes. I have been on several dives in the Northwest Indiana, Southeast Illinois area. Chuck Linder, who owns my local shop has 40 years of local diving experiance(he started when he was 10), and can give you information on the best wrecks on most of the Great Lakes. There is a great 2 book series out as well, " 100 best great lake wreck dives" that goes over the history of several Lake Michigan wrecks. If your interested in diving our area for such wrecks as The Tacoma, The Material Service, The Mackinac, contact me here or Chuck at the Scuba Tank and we’ll get you set up.BTW I have been in Viz over 60’ on Lake Michigan. Also on my buddy list is Milwreckdiver who lives in Wisconsin and would probably be more than willing to give you information about the great wrecks in his area.
