I've jumped north of the Arctic Circle a few times as a Smokejumper (in Alaska), but it wasn't much different than any other jumps I've done. I spend about five and a half months in Antarctica (South Pole Station), and honestly have no desire to make a skydive there. Too cold! As far as bad weather? I made a jump last year (again, as a smokejumper) into a rainstorm. It was'nt raining when I left the plane, and did'nt start until about 800 feet, but by the time I hit the groud, I was soaked! -smkjumper
