Yeah, we were looking over to the south facing rock with envy. We ended up trying yellowjacket tower, which is just a moderate rock climb in the summer. In the winter conditions, however, it was quite fun and gave some spicy mixed climbing for the few pitches we did. We ended up stopping about 30 feet short of the summit, which, in rock shoes in summer, would have been a very easy climb. With snow and verglas however it sent us packing despite or attmpets to aid it. As you said, it was good excercise, so it was certainly better than sitting at home.
