I checked the weather conditions last night before going to sleep and saw that it was 7 degrees out (according to Intellicast online) with a dew point of 7 degrees which means fog will form and freeze on surfaces instantly. This brings a smile to photographers because a nice thick layer of frost will form on everything. My car confirmed conditions were good so after I scraped off a thick frosty covered windshield I went out to look for frost covered subjects. This thorny branch was one of several things I found.
