Cache is near - but not exactly at the posted coordinates.
There are many different types of caches. This type requires you to solve a puzzle in order to find the cache.
This is a relatively simply quiz. Some puzzle caches can get wildly complex.
Here is the coordinates of the cache:
N 38 52.AAA
W 077 08.BBB
Now solve these problems and put your answers into the coordinates.
AAA = 009 + 200
BBB = 207 - 200
If you plug AAA and BBB into your coordinates, you should be able to go straight to the cache.
Ah, but this is a tricky one. Probably the hardest one of the day. Some caches are very well camoflages so they can be hidden almost in plain sight. And some caches are small. This cache container is both. Only the cleaverest will be able to find this cache

Cache is hidden in an Arlington County Park consistent with known Arlington County Parks geocaching policy. Please only search during park hours.
