Would things like fog contribute to shadow rays as well?

@reinaw1012 That's a good question. Participating media such as fog would logically reduce the amount of light that reaches different parts of the scene. In this case, we would want to gradually reduce the light's visibility rather than do a binary shadow/light check.
An interesting follow-up question: how would you render the fog itself, not just the shadows that it casts?
