Your road tar pictures would fit nicely into The World Atlas of Street Photography, Eric. In fact, I can't think of a damn thing that wouldn't fit into The World Atlas of Street Photography.
I've never been able to find the Ignore button. I'm not even sure I'd want to use it. I see a pathetic troll, too broke to buy the book he wants to critique, probably handicapped, confined to his room where his whole life is trolling fora like LuLa. He can't get out and make photographs but wants to join in the excitement of creativity. The trolling responses make me sad, not angry, so I'd hate to use the Ignore button. There've been other trolls on LuLa who obviously needed "professional help," and probably would have warranted the use of the button. "dalethorn" comes to mind. I'm not sure we don't still have a few. If I run up against one of those again I'll go hunting for the button.
We head for Florida tomorrow morning early, so I'll pretty much be off LuLa for a bit more than a week. Maybe I can get a street shot or two on the way down.
