Inside the convention hall, awaiting first lady's talk

I'm inside a chilly, dark convention hall where in about 90 minutes Michelle Obama will address this national gathering on volunteering and service. The lines to get in are outside and around the block, there are Secret Service agents everywhere and super strict security. I've got a seat right up front — and as I walked in I saw Jon Bon Jovi hanging out in the back of the room. He'd done a sound check earlier. I plan to get a few minutes with him after his show.
I'll also talk with actress Kerry Washington, who just took the stage to do a little pre-show speech. She has the unfortunate task of talking to a half-full room but she's doin' all she can to get people excited. Why Washington? She's an "ambassador" for L'Oreal Paris and speaking to the company's Women of Worth program.
Earlier today the first lady, in sneakers, capri pants and a jacket, went to a city elementary school to help volunteers build a playground and plant an edible garden. She inspired the group — some said they were teary — but she also took time to do a little of the heavy lifting, say hello to and meet the people who had come out on an unusually warm San Franciso morning.
