Metro Haiku

During my commute this morning, I started thinking about (and jotting down) haiku about the Washington metro.
I came up with three. The latter two really have to do with my evening commute, however, and I thought up a fourth on the way home.

Crowds on Orange Line -
At Ballston, I finally
am able to sit.

Vienna Station -

and there are no stairs.

From Crystal City
I take the Blue Line 4 stops
Then Orange Line 8.

Just now, the following occurred to me:

Does anybody see
me counting on my fingers
as I write haiku?
