I used to pack in a pack load of stuff. Don't do that anymore, I am a firm believer in the KISS method. Keep It Simple, Stupid.

Wind checker
1 Knife
Water
thermacell
scent elimination spray
grunt call
GPS
flagging tape

That's pretty much it. I have a bag on my stand that has my pull up rope and a limb saw in it, as well as a screw in step. I can carry that stuff in a small fanny pack.
