I don't hunt on the fly as much as I probably should.
My game plan in the hilly terrain I hunt ,is to concentrate on Oak ridge tops and perimeters of bedding areas.
They are always UP HILL. I pre set several stands before the season based on White Oaks and Beechnuts.
I hate carrying a climber up hill in the dark.
I could come in from the top but that's usually where the deer are , so I avoid that maneuver.

This year I hope to use my climber"on the fly"on a Game Lands I hunted during late muzzleloader season. The land is flatter and the bottoms showed alot of promise. The food is concentrated along the small streams and found multiple trails crossing them.
