Zombies! What are you going to do when...

[Raptor1]

I'm not saying a horse is not useful, but you're underestimating the value of heavy motorized transport, especially since you're trying to run a permenant safe zone with other people, where the carrying capacity of the horse would not be enough to bring enough supplies for everybody (Unless you manage to grow your own food, that is).

I suppose it doesn't matter much, if I find that my truck doesn't work as well as it should, I could probably switch it to something else; if you find your horse isn't working well enough, you could switch it to something else as well.
