Its been bitterly cold lately. Yesterday the wind drove that bitter cold right into your body. If any part of your bare skin was exposed it would instantly sting. The wind was not blowing today but the tempatures were still in the teens. So what a perfect day for a walk?!
    You have to watch your camera on days like this. If you allow it to get cold then bring it into a warm house, condensation will form inside the lens. Many say keep your camera under your jacket close to your body when outside. Then place in a plastic bag or baggie when you come inside and allow it to warm up slowly. Supposedly the condensation will form on the plastic bag and not your gear.
