Arrow for intermediate distances and I can fashion an arrow out of almost anything.
I'd fill the bat with concrete. The Chainsaw would need fuel, the blades can go dull and if I hit a zombie with them, they could get stuck, I can get just keep wailing on them braineaters with the bat.
I'll take the binoculars for long distance scoping. The flashlight would run out of batteries, the rope can be torn through easily, and the blades on the swiss can go dull.
I'll take the boat to travel over water. The Hummer consumes a shitload of gas. It's out. The dirtbike offers zero protection going through a crowd. The tank needs at least two people to properly operate and frick trying to fuel that thing. I'll find a bike if I need to travel. Keeps the cardio up.
