We finally have pictures of the elusive wigwag in Pittsburg, CA.
This wigwag protects one of the private roads at the Posco/USS plant. Unfortunately
the only way to get pictures of this signal is through a chain link fence.
Thanks to David Epling for tracking down this signal. I followed about
a week later to get some shots
of it in action.
