Tom Hanks is back in Oakland and his tweet of the Bay Bridge proves it

OAKLAND - Tom Hanks is back in the Bay Area and already people are inviting him over to dinner.

The 61-year-old actor, who most recently starred in The Post and is about to appear in the upcoming Mr. Rogers biopic "You Are My Friend," announced Thursday that he's home in Oakland, tweeting a fuzzy picture of the Interstate Highway 80 Bay Bridge sign as evidence.

As of about noon, he'd gotten about 1,500 retweets, 17,000 likes and 500 replies, many of them asking him to visit. 

His return to the Bay Area also prompted Kathe Hamilton to wax nostalgic about Hanks and share some class photos when she went to school with him. "Remember Mrs. Castle's class?" she tweeted to the actor, displaying their third- and fourth-grade class pictures of them in the now-closed Woodstock Elementary in Alameda, Calif.  (Hanks is in the third row, the fourth from the left.) "He was kind, smart and brilliant," Hamilton told KTVU. "Just like the character he played on Big." Of course, she admitted, she also had a crush on him as a child.

Hanks was born in Concord, Calif. and attended the now-closed John Swett Elementary School, Bret Harte Junior High and Skyline High School, all in Oakland. He also attended Chabot College in Hayward before transferring to California State University in Sacramento and then moving to New York City.
