Great thread.
As mentioned by others. My number one item is my wind checker. Nothing happens moving fwd without wind knowledge. Then it’s game on.
For me as I age it’s not so much about what to put in my pack as it about what to omit from my pack now days. I find myself packing stuff I’ve rarely or ever used.
That might be a thread of its own. “What to omit from your gear/pack”
I fully agree with this... My pack averages 5 pounds lighter then my dad's and I carry a liter more of water... He's 73... A couple years ago I went through his pack and took out a bunch of stuff I knew he wouldn't need... He could tell instantly it was lighter and couldn't figure out why... I finally told him him I went through his pack and asked me what I took out... I said if he could name it I'd give it back... He got one head lamp back... After the hunt was over I gave him back everything I took out... I think most of it's in his pack again...
