There's a cycle that I am trying to redirect just a bit, if not a lot. It's pretty simple.
It generally goes like this:
Factory => Distributor => Pro Shop => Bowler => Closet or Garage => Garbage => Landfill
So, what I would like you to do: Don't throw your ball away. There are many other uses for used bowling balls. You could give it to a bowler. You could ask your local bowling center or pro shop if they want it. Maybe you can resell it. Maybe you could give it to a younger bowler who can't afford a new one.
