Where do you think you'd last longer? With next to nothing of course. Siberia? Or Death Valley?
Death Valley isn't bad if you go the right time of year. Even in August, it just gets to 122ish and feels like you're standing in a humongous hair dryer.
I'm sure most places aren't that bad depending on the time of the year though. I wouldn't last long.
My joints would freeze up in Siberia. So I chose Death Valley. Plus, in a week or so, I could walk home from Death Valley.
