The results were staggeringly one-sided:
Slow: 237 (70%)
Fast: 98 (29%)
Real zombies are slow, but they're both only going to be stopped by aiming for the head. Always aim for the head, I cannot stress this enough.
And to my fellow Americans, happy Martin Luther King day. I believe building zombie survival kits for your community, when combined with mapping escape routes, counts as work toward this day of service.
