I am planning to go. See you there, if you happen to be in the area!

Google will be holding a hackathon to get you started on our JavaScript APIs! We will be doing short introductions of the APIs and then breaking up into groups for coding and camaraderie. There will be plenty of Google engineers present to answer questions and help you code along. Bring your laptops and come hangout at Google. Food will be provided. There will also be prize :)
