Where ya headin' to this weekend? Or have I missed it somewhere?

The only things I truly concern myself about the most are:

Bow & arrows
release
pull-up rope
quiver caddy I screw into the tree
screw-in bow holder if I'm not using my Summit climber which has one on it
treestand and steps if it's a fixed-position, or climber
safety harness
flashlight
knife

Everything else is gravy:

Grunt tube
windicator
odor-eliminating spray
binos
rangefinder
facemask
cap
gloves
camera & small tripod
Coleman lantern for tracking
game cart...

Then you start getting into some more "if I've got room" items, like my Primos bow sling, extra screw-in steps, extra bow holders, etc.
