So a simple suggestion here. What about basements in some houses? I have never seen one in game(so I assume they are not in the game). I dont know how common basements are in America. But here every house and even apertment building has basements (for every flat). A basement would be a good place to find many things, not usually found inside the house. So like hammers, nails, planks. Things not usually used in daily life. So this is a map suggestion.
