Scavengers are able to find things, get them, and get out again without causing a huge noise or mess. They are great at sneaking about quietly and always travel light. Scavengers are often trying to avoid confrontation. They’ll hide out, maybe build a little nest someplace secure, but aren’t likely to stay in one place for very long. They go where the supplies take them. The bad thing about scavengers is that since they are often on the move they are more likely to have encounters with zombies of all types. Out of those encounters they aren’t going to actually stop that many zombies. So it’s possible they would lead zombies into an area where you are hiding out or even back to their own camp if they are part of a group.
