Well, there are just a few very important items you might really have to have.
1. A good set of binoculars
2. A good range finder
3. A good thermos bottle
4. A thermo Cell
5. A never ending supply of cheese and crackers
6. The BuddyBo-Gotta-Go pee bottle
7. Several up to date deer hunting magizines
8. A green streamlight
9. A well practiced dog bark for running deer outta your hunting area after it gets dark so you won't spook em when you climb down.
10. And now we get to the last thingy you gotta have: A picturein your pocket of a really big buck just in case you don't see anything!

At least these are the things I have with mewhen I go hunting.
