Fascination is definitely most of it! Its also having an excuse to get out into the woods for some alone time or quality time with others. My 4 year old daughter loves to go out with me and asks me to go out a lot. Which I think is a lot better than her sitting at the house watching tv. It's a great work out and when you find horns it is really such a great feeling! Sometimes we sell them and certain ones we keep. It is fun to be able to just look at them.
