First time bow hunting or first time hunting?
Find the deer, get there without them knowing it, be prepared to shot one when they come by. Find where they walk this winter and pick your site, determine what shots you'll be most likely to take and leave, practice through the summer as you'll have to this fall AS YOU'LL HAVE TOO. Pick the day, get there very early and stand still using bino's to pick apart the landscape, see them before they see you. Make the shot count.
