The wall is definitly there..Have seen it alot since the barge was there...I agree, alot of people get to close to te shore line and hit the bricks there....I think it was only one barge that was there for several days...It also was a shallow draft barge, use pumps to fill it for ballast wen they where working on the plants intake. I was hoping to watch them take it out of there buit we missed it. I was curious as to how they did get thru there.
