We've heard that "Where in Castro Valley" photos have gotten a little easier. So this week, here's a bigger challenge: Can you name where each of these letters can be found on signs in Castro Valley?
Thanks to resident Nathan Parks for putting this together.
So tell us, where in Castro Valley can these signs be found?
