get your head up Rory, happens to the best of us. I had the same thing happen last year, the arrow sounded funny when it hit the shoulder of a pretty nice 8 point. Well I found the arrow and it had not penetrated very far. I looked for six hours that nite, walking circle with hand held spotlights. Looked again in the morning and found my deer all torn to pieces, coyotes had run it down.... The broken piece of arrow was there on the ground, and pretty much just fur... Really made me mad for a while.... eventually you just gotta get back out there, so good luck in the morning!
