This cache will take you on a short hike through two interesting location: You will pass by a memorial for those who died in the caravans of armored vehicles ("meshuryanim" ; משורינים) during the seige of Jerusalen (1947 - 1949). For more information check out this link and this link (in Hebrew). And then you will reach the ecological bridge (the "EcoBridge"), which is a wildlife crossing that allows local wild animals to cross highway 1 safely. It's 70m long and covered by 200,000 cubic-meters of soil. For more information (in Hebrew) see this link.
Now for the geocache.
The posted coordinate of this multi-cache will start you off at the trailhead where you can park. There are also some KKL picnic tables nearby. From there you will pass by two intermediate waypoints, and with the info you gather on the way, you will be able to solve for the final coordinates of the cache, which is near the EcoBridge.
There are many thorn bushes on the way to GZ, so it's highly recomended to wear pants
At the posted coordinates find a sign showing exactly 5 numeric commanding positions (משלט). The sum of their numbers is X
At the first intermediate waypoint you will see the preserved remains of several armored cars ("meshuryanim"). You can post a photo of yourself with them (optional)
At the second intermediate waypoint you will see a lone sign in Hebrew explaining the history of these armored cars. The number of words in the 3rd line (the one with parentheses) is Y.
Now you can find the final coordinates:
N 31° 48.[3*X-1]'
E 35° 3.[131*Y]'
The cache is a large ammo box. I started it off with a veriaty of swag items.
