Zak, how much scouting did you do prior to the season? I know you spent a lot of time with your bow, but how much time did you spend in the woods before season? My problem in the past has been not spending enough time before season in the woods.
I'm inclined to think the deer are using that specific area during the night. This early in the year the deer are still using their summer feeding patterns. Hunt field edges and staging areas and you'll be good to go.
Good luck bud.
