went down this morning but wound up on my back, breaking thru the ice. it's all good until it isn't, right? studded tires are fine, unless the tread fill w/ compacted snow, lifting you off the studs. I knew this water would be deep, in fact I heard "running water" in the distance! I stopped but as I put a foot down, I slipped & went down. made a little hole near the big hole, in front of the flooded area
