In theory, you'd want something on the fringe of where any less with a smaller aperture than f2.0 would struggle and result in some camera shake and increased noise (from the higher ISO).
That's what I said,"Maybe a city skyline at night, or a lamp post." A restaurant would probably be good. or a club maybe. I'm thinking of over places...a neon sign, and street sign. A sidewalk with lamp posts, a candle-lit vigil. hahaha
