I thought you may like to read this interesting report by Mike Bara on the Lunar Double Craters http://www.informantnews.org/modules.php?name=Content&pa=showpage&pid=23
It is quite along and involved report, but it does analyse the data and show how these are seemingly unnatural features of the lunar landscape and how they form part of a much larger landscaped area.
These double craters have been explained away as photo blur caused by the spacecrafts motion but this report here shows that it cannot be due to this.
