This winter has been an almost constant battle against snowzilla in Rocky Mountain National Park. I appreciate the equipment the park uses to keep the roads open. The immediate forecast is warmer, so the worst may be over. Canon EOS 5D Mark IV, Canon EF 400mm f/4 DO IS USM. 1/4000s@f/4.0, ISO 400, lens focal length 400mm., 2/4/2017 9:29am.
