Good luck finding the deer man...and don't give up. One year I found my deer 3 days later about 300 yards from where I lost the trail. It was a liver shot an apparantly I bumbed him too soon. I only found him because I entered by area from a different direction due to the wind and guestimated locations of the deer in our area.
Were you hunting from a stand or the ground? Was he broadside or quartering? A few more details and maybe we can help talk you through this man.
Another option is the free dog service thats available to hunters to blood trail and find their deer. There should be a dog available in your area. Most people just tip the guy if he finds their deer. Might be something to consider if you've already given it all you can.
I haven't seen a shooter yet myself. Will be hunting hard all week. Good luck all!
