That's horrible...not only is there paralysis (hopefully just temporarily) but sounds like internal injuries as well.  Let us know if you hear anything else.

You're absolutely right Brandon...if you're going to use a climbing stand or any kind of tree-attached device, or just climb into a tree, for goodness' sake wear a harness.  Years ago I knew a fella in East Texas that used a climbing stand but didn't use a harness.  One hunt he had climbed-up pretty high and apparently fell asleep as the day progressed.  By the time they found him he was dead on the ground.  What made it worse was he had a young family.

In fact I spent a couple days in the hospital when an attached tree stand came apart on me (I made the mistake of not checking the stand out before getting in it because it was dark).  Thankfully the stay was precautionary, and apart from a little blood in the urine and a few stitches no big deal.  But, it could easily have been much, much worse.

One other thing I'd stress is the need for following safe weapon handling procedures getting in and out of the stand.  Should something unexpected occur strange things happen with bolts, safeties, and arrows when falling through brush and tree limbs.

Have a great (and safe) hunt all!
