I’m at Google Mountain View

We have made it to MySQL Camp being held at Google Head Quarters in Mountain View California. Directions WOOT!!!

So we are at the lobby reception of Building 40 , and I’m lounging back in a large green beanbag behind all the name tags, this is so cool, the problem is with all our technology, nobody yet has the capability to read the photos from a digital camera so I can upload it. Both Sheeri and myself have left the right stuff in our hotel room. So stay tuned.

Leslie our Google co-coordinator wants her business card to read “Hacker Herder” which sounds so cool. This whole weekend is going to be a blast. More to come.
