Teri,
I too was "raised" by my stepfather... My father died when I was 3 1/2 and my stepfather came into our life when I was 6. He taught me to hunt and fish and at some point "we lived" the phrase; "In a moment shared my father became my friend". That moment(s) shared was in the field hunting and fishing.
I have no idea how I would have ever been able to "say goodbye" except through the thousands of memories, some sad, some funny and many very comforting. The best of the memories always involved us being out hunting rabbits, ducks or in a boat fishing... As I sit and type this to you my mind floods with all of those great memories.
You will never be able to fill the void that is left, but I can guarantee you this. Although you will miss him, those great memories will keep him alive in your heart and mind. He will never really ever be "gone". I think it is great that he passed on the love of the outdoors to you... because I know that that is what the truly great memories are made from...
The world will seem a little less bright for a while, but someday you will realize that the brightness is back... Every time you sit down in the boat... he spirit will remind you he is there...
Finally, I can't imagine many things better than to be outdoors hunting or fishing the moment this chapter ends and the next one begins... He must have been a very special person, indeed, to have been granted such a great ending... How lucky you were that he came into your life. You and his whole family and all his friends are in my thoughts and prayers. May God bless.
