Interesting thread. As I can faintly see the "autumn" of my bowhunting career looming just over the next mountain, and because I have no children of my own, I too have had this thought cross my mind from time to time. Actually, I have no real concern over what becomes of the man made "stuff"- my bows, arrows, quivers, portable treestands, etc., etc. that's just STUFF. My greater concern is for the "stuff" that was (originally) created by God- my mounts. Not that I have any more mounts than the next guy, but I do have a LIFETIME of mounts hung here and there throughout our home.
I once read Denny Sturgis Jr. refer to the mounts in his "man cave" as "treasures", rather than "trophies". That description has always stuck with me. They are indeed "treasures" and I do hope that in my passing they will end up somewhere where they will be appreciated.
