Spend the morning in lovely Lodi discovering the charming shops, boutiques and restaurants for lunch on your own. In the afternoon, we’ll head to the Haggin Museum, an art and history museum located in Stockton. The Haggin was called "one of the hidden gems of California" by Sunset magazine. The impressive three-story brick building has stood in the center of Stockton's lush Victory Park for 85 years, but it's what's on the inside that makes it worth visiting. The Haggin has just completed a $2.5 million renovation and is home to historical displays, lovely art and incredible local history. Register by April 3; call for availability after that date.
