A farmhouse, if properly constructed and secured, can be a viable alternative to venturing into a town or village hoping to find a secure building. For farmhouses near wooded areas or areas with rolling terrain, these areas provide their own unique advantages and disadvantages. Proceed with caution.
The disadvantage is that crops surround the farmhouse, and zombies can sneak up to the house without being seen. Makes sure to be vigilant. However, this could be an advantage as zombies might have a hard time cutting through the grass.
