I only ever lost one deer on an evening hunt. It was a doe. It was in the late season and it was cold so I knew the meat would not spoil. The only problem was I went back out the next morning and the yotes go to her first. There was a buck I shot right about sunset, but I heard him crash. I walked up on him about 1/2 an hour after it got dark. Sorry about your bad luck there. Hopefully you will be able to get back out there and enjoy some evening hunts.
