So after about 45 minutes of grassing him, he didn't look hurt and actually started feeding.
So I took off after him. Couldn't find my arrow, so off I went. I knew where I had last seen him so I went there.
Amazingly, still blood about 500 yards out, but not much. I trailed, glassed and trailed and I came up empty.
The worst feeling I ever have is hitting an animal and not finding him. I am hoping he lives through it, but I will be back to look again in the morning.
Ugly side of bowhunting.
I had packed a great lunch and realized I forgot to bring it.
