The purposes of this geoart series are twofold: to bring cachers to the watershed of the North Fork of the Broad River in Stephens and Franklin Counties and to serve as an introduction to the fascinating field of cryptography.
According to the historian Suetonius, Julius Caesar encrypted military messages by shifting their letters three spaces. For example, if Caesar wanted to instruct one of his generals to "ATTACK AT DAWN", then he would send the encrypted message "DWWDFN DW GDZQ". (Of course, we're pretending for a moment that Caesar and his generals spoke English...) D is 3 letters after A, W is 3 letters after T, and so on. Then the general would decrypt the message by shifting each letter back 3 spaces (D back to A, W back to T, and so on).
Of course, we're not limited to just 3 spaces. We could use 4 spaces, 5 spaces, or whatever. In fact, the "Additional Hints" on every geocache page are encrypted by shifting each letter 13 spaces. This method of encryption is known as a Caesar cipher or shift cipher.
To find this geocache, decrypt the message below using a Caesar cipher. You will need to figure out the number of spaces that are being shifted.
