I think I've figured out the difference between steps and stairs (at least as I understand them). Stairs are an unnatural form, while steps are built into, or are a part of their environment. I'd consider 10, 11, 13 to be steps.
Not that this matters to anything, just a mental ex cerise on my part. I vote 13.
That's what did it in the end. Not the money, not the music, not even the guns. That is my heroic flaw: my excess of civic pride.
