Every deer I have ever shot has been in the morning. First off, I stress the use of bright feathers and knocks to better your chances of seeing the arrow to know where you hit. After the shot watch to see how the deer is moving and remeber the direction and also listen to how it is running (stumbling around or running like hell) and also try and listen to which direction it is going. After a few moments of silence I climb down and go to my truck to head to town for breakfast or lunch. If however the deer ran in the same direction of your truck (which they have never done for me) you should probably wait it out at least an hour before doing anything, depending on the shot.
