Yes, that's me! I got trained to ice dive the first year I was certified (what else is there to do in MN in the winter) and got the drysuit for Christmas. Plenty of people ice dive in wetsuits, though. I don't know how!! Yikes, we'd go out some days when it was -10F. We had these big tents with porpane heaters to get dressed in. At the end of the season, the ice would be so thick you couldn't get through it with a 36 inch chainsaw blade.
