Having lived and worked in a few VERY cold places during the winter, the humidity is very, very low. Therefore, static electricity builds up, and you practically need a ground strap to keep from shocking yourself or someone else. You can practically create your own light show just by taking off your tee shirt with no lights on. Ha!
Thank you for sharing that. I have lived in the desert all my life and it is dry, but never extreme dry cold so I did not know that. Crazy stuff!
