used the heat pack method saturday. Opened the pack when I left the house and it was nice and warm by time i got to the cave. Threw it in the camera case and headed in. When I first pulled it out to take pictures, I was able to take photos immediately and the heat pack warmed back up too. no fogging of any kind, it was great! Thanks for the tip!
