On a day that was not so cold, I took a video of tapping ice. I find it almost irresistible to walk by a frozen puddle if there is white ice on top. Seeing white means there is air between the water and the ice. Tapping the brittle ice makes a crackling sound that is most satisfying. John was standing by, ready to assist. He gallantly offers his arm when the ice is thin, because I would get my foot wet if I lost my balance.
If any of you do this, please let me know. Finding a kindred spirit would be exciting.
