I always carry the following for day trip. Some of that stuff is sometimes shared between several of us:
- 5 to 10 ammos
- bino
- range finder (usually leave it behind because deer shots are always less than 150yds in the Northeast)
- camera
- 2 knives (1 for the deer, and 1 for my lunch). Don't use a contaminated knife for your food.
- knife sharpening stone
- water and snacks
- rifle
- shooting stix (not always)
- gps
- small first aid / emergency kit and toilet paper
- field gun cleaning kit
- pepper spray, game bag, gloves, etc.
- extra clothing as needed
