I have to agree with the rest. Call in DEAD if you have to tomorrow. Just go find that deer. I hit one too far back (yes guts) a few years ago. It only went about 200 yards and bedded down. I backed out like you did and went back the next morning. Found it in about 30 minutes.

You have done everything right so far by waiting. Don't blow it by waiting until 3:00. Like Matt said if taking off in not an option then go out at 2:00 or 3:00 in the morning.

Good luck and keep us posted. One of these wounded deer stories has to have a happy ending.
