8.20.06 Black and White?

I love this quick snapshot I took this evening at a playdate. So I decided to play with it in Photoshop. Ugh. There are 62 bazillion "conversions" (as my 2P's friends would say) to create a black and white photo.
I started with the original, and then added two of the three faves I came up with based on a couple of recipes I've read online. The last one is a simple boost done in Picassa with their editting tools.
What do you think?
