Thoughts lately are based on pets and transportation in the zombie apocalypse:
1) Why doesn't anyone on The Walking Dead have a dog? I feel like this would be a good early-warning system.
2) How about bicycles? Gasoline won't exist soon and highways are clogged anyway. Save what's left of the earth - ride a bike. Plus you'll build leg muscles and get good cardio - all useful later on when running for your life.
3) I'm always curious about why they don't grab a canoe and navigate waterways? It seems like an easy answer. I'm going to assume zombies can't swim and would be stranded on the banks while everyone floats by. Also I picture this happening to the song "Float On" by Modest Mouse.
