I knew it! Ugh but they always film their exterior scenes at night and rarely during the day when I drive by. On another note, the inside of the "hospital" is so lit up and visible from the street at night. Which is sorta funny because if you wouldn't know what you're looking at, you'd never guess it's a set.
