Unless you have resorted to a last ditch effort "Body Search" where you can use all the manpower you can get, resist the urge to bring everyone and their grandmother in with you to track your animal!
Tracking is best done IMO with 2 people who know what the heck they are doing. 3 or more people does nothing on a bloodtrail but get people in a rush, off the trail and sign possibly mixed up, disturbed or lost entirely.
Call that one other guy you can count on to go slow and work with you as a teammate on the trail andTHEN call everyone else after you've either found him, or exhausted every effort to find the animal yourself and you need to grid search.
That's right up there with the best tracking advice there is. I prefer to track my deer by myself or with a VERY VERY VERY VERY VERY etc.... experienced hunter and that's IT!!!!! Nobody else cares as much as you do about recovering your deer. Too many bodies is nothing but trouble. Last ditch grid search is the only time I'm rounding up the troops.
