Halt! The actual cache is not here..... You are looking for a sign. One of the letters will give you the direction. To find out how far you must travel, you will have to mirror a set of two letters. This will give you the last two digits. To get the first digit, apply a divisor of 4 to the numerical value of the remaining letter and reduce it by 4. This will give you the distance in feet.
Congrats to terrykr for FTF!
