welcome to the board,

I' m new also but I can tell you one thing, If you don' t know just ask.
Being fifteen years old means you' ve got a lot of trial and error ahead of you with hunting. I know I did, mainly because there wasn' t a place like this I could come to ask questions or to share what I knew about hunting. Take advantage of it and anybody who can answer your questions will and don' t forget to throw in your two cents, that' s what makes this whole thing work. Who knows you might even make a few friends along the way!
Good luck and welcome aboard.
