Really enjoying dynamic for the fact it makes a tamable wilderness so to speak. Once you have rid the area of the zombie pool eventually you have an entire town worth of materials to fall back on and a relative safe-zone. But at same time it’s a challenge doing it!
For fires I just place some wood splinters plus things like boxes and wrappers in a pile then set them alight with matches. Just trash stuff I have no need for or break up furniture time to time if needed for fuel.
