Many of you may think we are crazy, but we have recently taken up caving. For the record, we have and do take every safety precaution that we can, and go only in groups mostly consisting of professional cavers (these are the guys that create the cave maps and serve on rescue teams). I don't have many pictures but here are a few.
Yes it is snowing outside and we are wearing t-shirts.
Looking down into the cave...
The cave was about 70 degrees. You can't tell in the picture but it was actually steaming.
