Your retaining wall... I voted against it in the officer vote because I couldn't see anything one way or the other from the picture and asked for something I could see. I'm careful to give a detailed reason why I decline when I have to decline so people know. When you resubmitted, I left it alone because you didn't improve your photography at all. Just one distance, blurry picture that doesn't show me anything and I really needed to see something more. So, hey, I'm glad it got approved and you can move on. You should be glad that I decided to leave it alone.
