I would do the individual quote thing, but it's almost my bed time.
2. It's hard to tell before you get there if they've gone freelance. If you're sure they're still in protection mode, then it's probably worth the risk. Be advised that you will probably be digging latrines and other unpleasant jobs.
4. Ok, properly dispose of then. Make absolutely certain that a corpse doesn't reanimate or that the body itself won't cause other issues, such as disease.
5. As I said, do it at a distance from your location. If the poor sod is gonna die, take him to the other side of the river. If you don't like the flames, other zombie traps are available.
6. In the example from Land of the Dead, they could have dispatched lots of those zombies without wasting ammo. If you see a solitary zombie, destroy it. The biggest menace from zombies is when there is a horde of them. You don't want to pass up the opportunity to prevent hordes.
8. I'll take the high ground. Zombies can't fall uphill. They can fall into your subway tunnel, or swarm around the entrances so thick that you can't cut your way through them.
10. Valid point. There are lots of other uses for urine, but if someone has no idea what to do with it, they can at least save their water for drinking.
Your feedback is greatly appreciated, as it is constructive in nature.
There is Rule 13 (it's always 13 in my rule list), Be willing to let others die. If they are a drain on your resources, you might have to use them as zombie bait or send them on their way. Everyone has to be useful in one way or another.
