After i read the book ZODIAC i could not sleep. It's so scary! Especially the part when he said "I'M GOING TO STAB YOU TWO" If you saw him in your backyard what will you do?!?
Good grief! I saw a couple of movies about this fellow.
If I saw him in my back-yard and was still alive after I woke up out of my faint. I would call 911 and grab a baseball bat and wait until the cops got here.
Then I'd change my underware.
