In this Straight and Arrow puzzle, instead of no two black cells being allowed to share an edge, every black cell must share an edge with EXACTLY ONE other black cell. The rules are otherwise unchanged.
As as few of my readers have noticed, I've finally gotten around to adding sharing buttons to this blog, including Google's new +1 button. They are located very unobtrusively just below the title of each post, in the "Posted on July 4, 2011" line. If you're a long-time reader and there are older puzzles you found particularly memorable, feel free to search the archives for them and +1 them!
