If I am permitted to do something about the hot or cold, I'll go with cold, since I can layer up and get more comfortable. You can't really layer down past your skin when it's too hot. If I have no control over it ... cold, I guess, cause eventually I'll just pass out.
There's one with BBQ pork, onions and cheese I get here that is very good.
