Hi Price -

I don't see a category for this problem, though it certainly seems to qualify as a data error. This post of 2005 takes you to a road in California with the entire bike route covered in identical placemarkers. When you zoom in close, they even multiply. Since this member has only 2 posts to his credit, and this isn't a folder, it's unlikely he posted all of them. There are even a few of the same markers at random places away from the road.
