A dove.
My grandfather went into a home for Alzheimer's and I inherited his 20g, his .22, his hunting knife, and a few other things. The following weekend I took papaws 20g squirrel hunting in remembrance of him but there were no squirrels to be seen. However there were lots of dove and my best friend said he hadn't ever eaten dove and asked if it was good to eat. So, we started dove hunting. As this was the first animal taken with a new to me family gun, it was a very special animal for me. I'll always remember it. I know it isn't an archery kill, but it brought back a ton of memories and getting to share that hunt and kill with my best friend made it a fantastic day in the field.
