I’d like to get as many people to review my overlay of the Halloween Card and the 1st confirmed Zodiac murder at Blue Rock Springs.

There were several things I noticed about the skeleton on the inside of the card;
1) The feet in a triangle were bizarre, I certainly think it’s a clue to either triangles or a Mt. I’ve never seen a skeleton with feet positioned like this.
2) One of the "eyes", (which I believe are disguised as "C’s", as in Clues is exactly similar to the Columbus Parkway that cuts through Blue Rock Springs.
3) The skeleton reminded me of the outline of the SF Bay. When I turned the skeleton upside down, the pelvis fit in the North Bay and the upperbody fit in the East Bay. Even the leg bones mimicked the Richmond Bridge and GG Bridge.
4) both hands are somewhat hanging from the San Mateo Bridge "posts" at Hayward and San Mateo.

I’ve mapped the "eyes" to known Z sites, Blue Rock Springs, LHR, even an area that (thanks to Sandy for pointing out) potentially Kathleen Johns was driving around.
One of the "eyes" is also positioned near the Antioch Bridge. Sandy also mentioned a Nurse committing "suicide" from the Bridge sometime between (1969-1970).

Could Zodiac have been giving clues to his 13 sites?
Is the angle that I have the Halloween Card overlayed have the "O’ in Boo even close to be set to Mag. North?
