A great question from my good friend Troy!
As you have aluded they are all meaningful and special so choosing one shouldn't take away the significance of all the others.
There are two that come to mind for me.My first bow kill in my second season of archery hunting,an eight pointer that I had seen exactly one week before from the same stand,I new that he was bedded close by,I purposely circled the area to come in to my stand from quite a distance,I didn't want the wind to have any chance of blowing my scent in to his bedding area,he came out just like clock work the same time as the week before but this time about ten yards closer.I shot him at 37 yards,he went about thirty yards and crashed.With the exception of my Wedding day and the birth of my daughter I have never been happier!
The second one ties in to the first for me.I had a mentor and a friend who was an exceptional hunter (by practically everyone considered to be by far the best in our area)after shooting that buck,I couldn't get it to his house quickly enough,I was so proud.He was so pleased for me! I asked him how his season was going and I had all I could do to get him to admit that he had shot a beautiful eight pointer,my buck was a nice deer but his was exceptional,I had to practically beg him to see it,he didn't want to steal my thunder.This man "was" the best hunter and woodsman that I have ever known and as rugged as they come!
This past september my above mentioned friend died in a truck accident while hunting Elk in Idaho,he had arrowed a 5x5 earlier in the day and had it quartered in the back of a pick up truck that he was driving.While driving he got his tires in loose gravel on the side of the road and ended up going over an embankment,he died as a result of the injuries suffered in the accident.My sadness was overwhelming,Stan was larger than life to me,I couldn't imagine any thing being tough enough to kill him!
In our area killing a bear with a bow seems to be representative of joining an elite rank of bowhunter,Stan had killed three or four over the years,and I supposed if he was so inclined he could of killed many more.Well this fall I arrowed the first bear I have ever taken,and some how I can't help but think that Stanley in some way had something to do with it,almost like it was his gift to me.In my mind the bear will always be Stanley's bear.(I will get pictures posted of the rug)
Just as an eerie aside.The morning of Stanley's memorial service I saw the biggest buck I have ever seen from my house making a scrape.In the 12 years that my family has been in our home I have never seen a buck that big from the house or seen one make a scrape from the house.It gave me chills!
