To start with, good luck on your first archery season. It's a blast. I carry snacks, water, and Gatoraid. A couple of large ziplocks, a dragging strap, my knife, some orange marking tape, a small flashlight, two light weight orange vests (one for me, the other for any deer I have down). This is all I can think of off the top of my head. I would suggest one of those fancy shoulder harnesses for for binoculars. They keep my binos close by and up against my chest when I'm shooting.
A lot really depends on where I am hunting. Some areas I know really well and don't stray more than a mile from the truck. I don't take much on these trips except, snacks, marking tape, water, knives (2), compass, matches/lighter, head lamp, wind indicator powder, a pen and rope. It all fits is a small fanny pack . Other trips if I am not quite sure of the area (could get lost after dark) or I am hunting a little farther from the truck I also carry basic survival gear, foil blanket, more food, more water, rope saw and a few other odds and ends to make it through the night if I had too. Fits in a small day pack. If it's a full on backpack trip, well, that's a whole other story for gear.
Get a pack that has a pocket for a camelback, and it will help tremendously. That way, you will have a hose to reach your water. I always pack as if I could get lost, so I have extra protein bars, first aid kit, extra knife, extra light and batteries, rope, compass. Course, that's just my opinion...I could be wrong.
I go with a Camelbak mule (desert camo) for my javelina hunts in Arizona. Some other light (pocket camera, maps, GPS) goes in the cargo pockets of my pants or outer jacket/vest.
The Camelbak holds a skinning knife, paracord, compass, first aid kit, survival blanket, energy bars, matches, lighter, etc. Ever since a short day hike turned into an overnight survival situation several years ago, I pack light, but I pack like I'm going to be stranded for a day or two.
IrishLad, please PM me when you get a chance. I'd like to chat with you about upland birds around Cedar.
