I passed along the story (as I'm sure hundreds of other outlets did) of young Miles' battle with leukemia and his wish to save Gotham City (San Francisco) as Batkid.  Today is the big day, and you can follow a live blog while Batkid's heroic exploits unfold.

Watching the live blog and seeing the thousands of people turning out on the streets of San Francisco is remarkable.  Celebrities, politicians and everyday citizens have tweeted their encouragement throughout the day.  You can follow the blog yourself and watch the story unfold.
