Illegals Crossing Sign

Wow.  I've truly been away from home (California) for far too long.  I just discovered this sign for the first time recently (on VE3D.com it just so happens).   It really bring a lot of different thoughts to mind.  Anger, laughter, frustration, annoyance... but wow.  They really have a sign for this to warn drivers to help avoid these people now?  *shakes head*  I'm actually not clear if this is California or Arizona, but either way...

UPDATE:   Never mind.  I found references that make it clear it's in California.
