Fingertip tip: For those coming from warmer climates. If your
fingers get cold, stop, take your hand out of our pole strap,
and swing your arm rapidly in a circle. The centrifugal force
will draw blood to the fingers warming them up. Fingers are
the second worst place to get frostbite.

Hmm. Does the same technique work for the worst place to get frostbite?

man, the things you learn on this newsgroup!
