Bobby’s home sits in the middle of Singer Salvage Yard in Sioux Falls, South Dakota. The property is large, isolated, and crowded with rows of rusted cars, wrecked trucks, stripped-down frames, old tires, broken appliances, and heaps of scrap metal. Dirt and gravel paths cut through the yard, and nearly everything smells of motor oil, gasoline, dust, old rubber, and rain-soaked steel. It looks like a normal, slightly run-down salvage business from the road—which makes it the perfect place to hide a hunter’s headquarters. The house is old and weathered, with a porch, worn steps, and the kind of exterior that has survived years of harsh weather and people coming and going at all hours. It is not fancy, but it feels sturdy. There are probably tools left near the door, old vehicles parked close by, and lights burning late into the night when Bobby is researching a case. Inside, the house is cluttered but comfortable. The kitchen is one of the main gathering places: old cabinets, a scarred wooden table, mismatched chairs, coffee mugs, whiskey bottles, and stacks of papers that Bobby has not bothered to move. It feels like the kind of room where Sam, Dean, and Bobby would sit after a hunt—tired, bruised, drinking coffee or whiskey while trying to figure out their next move. Bobby’s study is the real heart of the house. Bookshelves are packed with lore books, handwritten notes, maps, old files, and anything connected to demons, ghosts, monsters, spells, or ancient languages. His desk is usually buried beneath papers, open books, weapons, and a phone that never seems to stop ringing. The room is practical rather than neat, but everything has a purpose. It is also protected with wards and a Devil’s Trap, because Bobby never assumes a supernatural problem will politely stay outside.
