There's the thing. You stated your opinion, so you received an opinion. There is a difference between "freezing cold" and cool/cold. You're not sticking the animal in sub-zero temperatures, or temperatures below 50F. Its more around the 60's-70's. They are not build like us either, so they do not react the same way as we do to cold or cool temperatures. It is much less stressful to both snake and the photographer to cool them, and have them sit still, than trying to repeatedly manipulate it to get your shot. Less energy burnt for both as well. Makes more sense than picking the snake back up over and over, to try and get your shot, wouldn't you think?...
If you wouldn't do it, thats fine....but the moment you state your opinion on an open board and thread, is when it becomes arguable, or open to criticism.
