I’m a fan of churches, if near enough to water. Stone walls, lots of benches to disassemble, the little naves off the corners make great crafting rooms. Good even to start, with braziers for cooking. All the windows are a pain in the tuckus, but after they get boarded up it’s pretty safe. Until midnight telepathic teleporting Zombears start appearing next to your bed and gnaw your noggin.
As a side question, why Zombears, but not Zomooses?
