Look man you want to kill a late season pressued buck that you have done zero scouting on and have no clue where he is or if hes still there. I have told you what I would do but your looking for THE GUARNTEED answer but havent done any of your homework. Next season if you are doing a late season youth hunt you HAVE to do your homework. I still feel you got some great advise here and what we said is the best course of action to be success givin the senario you discribed. Thats why its hunting man, So get out there and make this a outstanding hunting experince for the youngen. It will be a thick brush hunt if you want to find him. Get in there early catch him moving about when he thinks your still sleeping.
Good Luck
