Every season has been in a "hot" area. I would not mind them making a season in a cold/winter area. Something like Tierra del Fuego, Tibet mountains, Greenland, or whatever. I'm sure the producers can find somewhere good. I guess the main issue is water with below freezing temperatures and the increased danger of illnesses, but isn't that the whole premise of Survivor?
P.S. Sorry if this has been discussed before, I haven't been around lately.
