If this is your first buck ever... you are in for a dandy. Sit back and enjoy! Like many said on here already, don't set up too close to his trail and MAKE SURE you watch your winds and scent. Set up a pattern schedule that he is on and make sure you are in the woods 1-2 hours BEFORE you know he'll be coming through. Now that being said, don't be disappointed if you hunt the next 20 days and never see him! Deer are funny that way. Good luck
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
