If I'm bowhunting I rarely stay out all day so I'll just bring binoculars, and grunt call, both of which I carry around my neck, a knife, flashlight, and rope. Of course my bow and a quiver with a few arrows.

During the gun season I'll add a GPS and some sandwiches, snack bars, and drinks. Depending how deep I'll be hunting in the woods I might bring matches, and a space blanket too, but ussually I'm hunting farms and smaller wood lots.
