To find the cache the following equations must be solved.
The cache is at N37° 49.abc W122° 03.def
a= Jack has a dozen apples. He eats one and gives three to Terry. How many apples does Jack have left?
b= A * 0
c= 4 * 10 - 30 + 5 - 15
d= Mika is 10 years old. Candy is 2 years old. Tom is 1 year younger than the difference between Mika and Candy. How old is Tom?
e= a - d
f= e
The cache is a slightly camouflaged ammo can (received from Marky and Joani a long time ago ). about twenty feet off trail. FTF gets the attitude :) (you'll see when you find it). You might want to bring long pants, or something to cover your knees.
I believe most kids can solve the puzzle. It is my experience that a kid able to solve the puzzle should be able to make it to the cache. The cache is over a mile hike though. Adults are more than welcome to find the cache, there are trade items that an adult might enjoy also.
