Holiday Lights Map: Find the Best Decorations, Post Yours

Who's got the most festive holiday light display in the unincorporated areas?

It's time to find out. If you're proud of yours or your neighbor's post it on this map.

As the decorations light up the map, you can create a driving route through Castro Valley, San Lorenzo and even other parts of the East Bay to see the exterior holiday decor with family and friends.

To post a marker, click the "Add" button on the map. Or you can also e-mail the info to analisa.harangozo@patch.com.

And if you feel your display is truly outstanding, post photos and videos of it in Patch's Deck the House contest for a chance to win $100,000 for your local schools.

Check in with Castro Valley Patch for further details on the big contest, which begins Dec. 8.
