I too just noticed the sign. I'm wondering if they just recently changed the picture which is why…Read More we are all just noticing it if indeed it truly has been there since the 80s.......I certainly hope that it is an old sign and that this is not the beginning of other billboard signs lining our 680 corridor.

There has been a sign there for years, this just a new image at same old location.
