Upon further review, I can see what you are talking about now, coop.
I was going to argue with you for a minute, but I knew better. Once I got the right angle, I could see just the ever so slightest depression where it was polished. Good call!
Actually, the polishing runs the entire length of the base of the memorial. Seems much deeper on the left side of the memorial base and above and to the right of the area in question, and to a lesser degree on the right side of the memorial base. But, I see it now. Learn something new every day!
Thanks coop!
