Stemming from a story ya'll may or may not hear later:
Back in the day I was a better than average tracker.
Not bragging, just know that I left my house at 9:00 at night to help find a deer many many times.
I got to where, I could tell within the first 100 yards of a blood trail whether or not I was gonna find the deer.
Not one time did it go different than I "called" it in that first 100 yards.
Is there any mistake more common or more costly than getting on the blood trail too soon?
I absolutely can't think of anything that is worse.
Yes I have done it but learned quickly that is the absolute WORST thing you can do.
Others I have seen are:
1) Not sure exactly where the deer was standing.
2) Not sure of where I lost sight of the deer.
3) Too many "helpers" walking too fast and stomping out what might be the only pindrop of blood, or turned over leaf that would be your only clue as to which direction the deer went at a turn.
4) Trying to move too fast on the blood trail.
5) Not doing your job if you are assigned to stay behind the tracker and scan the area 50-100 yards all around you for a movement or bedded deer.
6) I "figure" he went this way......
What else?
