Where Is This?

[Lamplighter]

OK Merc, I give up. that's even a tougher one.
I'll have to leave it to one of the experts to figure out this one.

I found nothing in searches on "Louisiana Dungeness"... except pics of crabs.

So finally I cheated and did a Google Image search on my pic.
It found the pic in just one woman's travel blog.
Somehow Google had led me very far astray.
It was only half right.
