I thought you'd never ask!
So, do you do some northeast diving, or just on vacation to the "hip" places? I have a buddy who ice dives lakes in a wetsuit (he's an Eskimo, what'd you expect?!). As much as I love the warm climate stuff, there are really some good northeast spots if you go at the right time of year. I also hear Canadian lakes are warmer and more interesting than one might expect, with plenty of wrecks. I haven't put this to the test yet, however. Still, it's no substitue for the Carribean! Gotta make more time to to get away and get wet.
