I dive mainly around Cape Ann too. (I live in Saugus). I survived down to about 38 degrees in a wetsuit, but I was cold and started sucking air like a hoover. My little brother has a DUI TLS350SE that he bought a few years ago, and I don't think I could pay him to put on a wetsuit. I'm still diving on a 2 piece 7 mil, and hoping to move into a dry suit next year. My wife is going to take teh plunge this spring and get certified, and she is always cold, so at that point justifying a dry suit should be a little easier for me. There are about 30 or 40 really good dive sites around Cape Ann and slightly south, although I tend to dive where I think I can find some lobsters. There are a bunch of wrecks within recreational range, like the Poling, the Romance, the Nina T, and the Gannet, but some are harder than others due to location and currents. If you have a chance, dive Egg Rock just north of Misery Island & Kettle Island. It's a pretty good time. I myslef am looking forward to joining the ranks of the CAD's
