Dan, what I picked for you is the riggers climbing the spar tree at the Deming Log Show in Deming, Washington. It's a benefit every June for 'busted-up loggers,' your body just gets worn out over the years of using it SO hard...
People come from far and wide to see this stuff, all the unbelievable strength and skill of logging! Oh and btw, women do this too...run up the tree...not many of them, and they are never as fast as the guys (I think because women have a different center of gravity) but everybody loves the lady loggers and cheering them on!
