The helicopter landed at Canada College in Woodside, and the president traveled by motorcade to Mr. Doerr's home.
Almanac reporter Miranda Simon captured the scene near Roberts market where about 35 people gathered, waiting to get a glimpse of the president:
"I don't think (I'll see President Obama). They're probably not going to turn the lights on and roll down the window," says Sue Bishop.
Justin Pretre, 5, looks at a laminated black-and-white poster with pictures of all the presidents of the United States.
"He wants to see George Washington and Abraham Lincoln" says Tina Lount, his mother, carrying 3 year-old Landon on her shoulders. "Why do you like Abraham Lincoln?" she asks Justin.
"Because it's his birthday soon," he responds.
The two toddlers are wearing matching green raincoats. Their cheeks are flushed because of the cold.
Ms. Lount points to President Obama on the poster. "If you look real cute," she says, "maybe he'll wave at you."
Lauren Giurata, 15, says she was getting dinner with her dad when they saw the sheriff's patrols and asked them what was happening. When they heard the president was coming they decided to stick around.
Just then, the motorcade comes through: An ambulance, two armored vehicles and a few black Escalades. People start whispering, "That's them, that's them"
After the motorcade, Ms. Lount says Justin was disappointed he didn't get to see Obama.
"It was only cars," says Justin.
"What did you expect to see?" asks his mother.
"The whole president!" he says, raising his arms.
"I think I might have caught a glimpse of him," says Mia Ferrari and excused herself immediately: "I have to Facebook this!"
