Black and White Wednesdays

I really struggle with black and white conversion, so this is a great challenge for me.
Long Road to China (which sidebar, is originally an adoption blog - inspiring!) has a weekly B&W photo challenge.
This is a photo from April I recently tested my conversion skills on. I personally am drawn to how light and airy it is. I tend to go for high key conversions, either lots of white or lots of black. What do you love about black and whites?
