Simply go to your camp home page and click on the Notables tab. This is where are your most wanted game is tracked. To add a new animal, simply click on Add new Notable and follow the instructions. Once you have entered an approximate age, BGL will automatically age that deer. Something you had added at 1.5 years old this year will automatically be aged to 2.5 years old the following year, assuming nobody bagged it. If you have harvested that deer, it will automatically be placed on the deceased list.
