I think it started after seeing Dave Carrick's "Metal Stairs" and "Mexican Dive Shop" photographs on PBase.com that I felt inspired to search for similar examples.
So far, though, Carrick's still set the standard - in my opinion.
My collection seems to be developing in a more abstract / black-and-white direction...
Doesn't anyone like what you've done? Well, I do (and I'm not "fishing" for comments or votes). Another vote. BTW I checked out the "Metal Stairs" link. Great little gallery and thanks for mentioning it.
