RE: New hunter - first time out, got NADA
That's awesome! Don't expect to kill deer every time out. Heck I've hunted 7 times this year and still haven't even SEEN a deer yet LOL. Bowhunting is a challenge, but that's why its so rewarding.
As far as treestand go, I hope you were wearing a safety harness. And I hope you were using some sort of linemans belt while climbing and descending. I know that I'm much more relaxed when I'm safe. Good luck.
