I used to carry a folding saw, clippers, a range finder, flashlight (large 2 celled D batteries) rattling horns, extra jacket, particularly arain jacket and hood, extra knife, and some survival stuff like matches, compass etc.
It dawned on me (finally) thatsince i walk from my front door about a half mile over to my hunting area and I am hunting in stands where I've already clipped etc., I don't need that stuff with me anymore.
I carry a small "mini-mag" flashlight, a small grunt tube, and one good knife. I do also carry an extra string and sometimes in really cold weather, a balaclava (sp)? Oh, and I wouldn't think of going without my small binoculars---my 71 year old eyes appreciate the help. All that other stuff gets left behind and if I really need anything, I can usually just walk home and pick it up.
