Mine is because I am surrounded by noise all day and I often seek solitude and quiet, which is why getting into the outdoors is important to me-- Gets me in touch with the primal part of me, I guess. Kind of like poking a fire... very relaxing. Plus the first two letters are my initials, for Steve Horne.
Keep close to Nature's heart... and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.
