For whatever reason, I am particularly craving holiday spirit this year. I know of Thuroughbread in Alta Loma/Rancho Cucamongs, the Festival of Lights at Riverside's Mission Inn, The Nativity Scenes on Euclid Avenue in Ontario, the Euclid Star, and The Living Nativity at Granite Creek in Claremont. Google/maps is advertising this, which could be an interesting way to pass time.
Can you recommend anything else? What are your favorite holiday traditions?
