Try "teaching" a class of middle school kids in 99 degree heat, full humidity with no AC. Not fun!
Anything's within walking distance if you've got the time.

About the worst hiking conditions I can imagine is 90 degree or above heat or minus 0 and a 30 mile per hour wind. I would still take the cold over the heat any day!!!!! My choice is 20-30 at night and 50-55 during the day. Perfect!! Also can carry the kind of food I like to eat into the backcountry without the worry of spoilage!!!
