I was just at Mt Diablo a few weeks back! I conquered that mountain years back. But i've always remembered the zodiac when there. Fun fact time! The Mt Diablo picture actually gave coordinates to where he lived in San Francisco (if you included the code and the coordinates of his first known killing in San Francisco). If you went in his high rise apartment there was a telescope. It was focused on a grave across the bay in Oakland. Mountain view cemetery. Guess whos headstone it focused on???? C'mon lets play!
