Getting close to the season and I'm sure many are more skilled in this area than I am but as I age I learn. Add input and information for tracking that could help out. 1) I always carry orange or pink flagging to tie to trees or branches to mark the trail as I go just in case I loose blood. 2) Give the deer plenty of time before you start. Mentally mark the spot where you hit the shot and where you last saw the deer run. This looks different from the ground than it did from up in a tree. Blood color gives a hint as to if you should wait several hours or get started. Bright blood good, dark blood needs lots of time. 3) If the weather is warm enough, look for daddy long leg spiders, they are always attracted to the blood and help find that fine spray when it's hard to see. 4) Move carefully, turned over leaves could cause you to loose a track. 5) Look higher than just the ground. Grass, leaves, the sides of trees etc could have blood spray on them. I'm sure there are many more ideas out there, add to the list and we can all maybe learn something.
