I do it because being outdoors year round is what keeps me going. I hunt, fish and live to be out there. I'm a year round fisher and dream about spring, fall and winter fishing most every day. Summer not so much, I could skip that season all together even though I used to do bass tournaments, yuck.
If the day comes I am unable to do those activities then what's the point of my being.
I don't see it as an addiction ( although the gear buying is ) its just a way of life for me and grateful to have a wife of 28 years that understands
