What time of day did you see him? Yeah stay up in that thick stuff with him and sit until you can't sit anymore. He's in there, be patient. Don't over hunt it and don't push up in thereso far that it runs him outta there and gets your scent all in there. It's hard to let it rest a day or two when you know anice buck is in there, but do your best to skip a couple of days every now and then.Are rifles allowed in your state? Anyways keep at it, maybe you'll see him again.
Good luck
