When I was younger the block my grandparent's lived on all put up huge light displays for Christmas. The closest thing I've found here is the Festival of Lights at the Mission Inn.
I've gone every year for the past 5 years to see the lights, but never attended the switch on ceremony; so today I went to watch them turn on nearly 3 million lights and begin the Christmas season.
It was a great event, crowded, but fun. The lights will remain on until January 2nd, along with the Inland Empire's only outdoor ice rink. Kids can also visit Santa's and his reindeer, and decorate their own cupcake from Casey's Cupcakes.
