The Mid-World Bowling Bag is the bag that Jake Chambers found in the vacant lot. Its side reads, "Nothing but strikes at Mid-Town Lanes," in the Keystone World, but in Mid-World, it says "Mid-World" instead of "Mid-Town".
The bag was used to carry and transport Black Thirteen. In the side pocket, Susannah Dean found the sköldpadda.
"I do not aim with my hand; he who aims with his hand has forgotten the face of his father. I aim with my eye.
I do not shoot with my hand; he who shoots with his hand has forgotten the face of his father. I shoot with my mind.
I do not kill with my gun; he who kills with his gun has forgotten the face of his father.
I kill with my heart.”
