I saw the one at Sherman Way and Woodley (mid SF-Valley), southeast corner, above the 7-11, facing north. It's definitely authentic and it is EXACTLY as the one depicted above. If vandals got to the signs, they defaced them absolutely identically -- which is basically impossible. If you go looking for it, make sure you get WoodLEY, not WoodMAN or WoodLAKE, which are also SFV north-south streets.
John & Ken (640 KFI-AM, which is also a Clear Channel station), raised hell about this on the air the other day, and have attempted to get hold of the Clear Channel coworker behind this treasonous stunt.
I emailed it to John & Ken on Monday because I wasn't sure if they had heard about it yet. I also emailed Clear Channel.
