The County Asylum was a sanitarium in Hill County.
On October 26, 1985, in the timeline where the alternate Emmett Brown had been committed, Doc disguised himself and traveled to the asylum where, posing as his counterpart's distant cousin, Mr. Von Braun, he bribed the asylum nurse to talk with his alternate self. He discovered that, at some point after being committed, his counterpart had been lobotomized.
