NavySparksandtheMrs: This was a neat cache (if I don't mind saying so myself) while it lasted. It even was featured in the San Francisco Chronicle a short time ago.
Sadly it seems the city has cleaned up the immediate area taking the ammo box and what hid it with them. (Not the first time the city of San Carlos has muggled my caches!!!! Grrrrrr!)
I have decided to archive the cache and hope someone else will find a place to hide a large cache in this area of the park.
It was fun while it lasted.
