Just a sugestion for you guys have you ever done the 1000 Islands on the St Lawrence river in NY and Canada unlike the lakes the St Lawrence dosn’t have thermocline the vis is great and there are hundreds of well preserved wrecks. I dive this area several times a year. This was just a suggestion for you all, but if you go to the Great Lakes and dive Erie any where near Buffalo get in touch with me if I can arange the time I’ll dive with you.
