Bobby's Storage Unit
Following the destruction of Bobby's house by the leviathan Edgar, he tells Sam and Dean that he had copies of many of his books stashed around the country. On their next case, involving Osiris, Bobby does research from a storage unit. he has a desk, chair and lamp in the middle, as well as many books, and jars and containers which may contain elements required for spells.
The storage unit is No. 032.
Sheriff Jody Mills packs up Bobby's storage unit and brings the boxes to Sam in Canton, Ohio so that they can research Dean's disappearance. There are over twenty boxes, and Jody speculates that Bobby "may have been a bit of a hoarder." Amongst the books and papers there is also a bottle of bourbon from Rufus.
