  Silverback Cipher  
 
Silverback hunters should be familiar with the “pigpen” or masonic cipher, which is a simple substitution cipher exchanging letters for symbols based on a grid.

This cipher can be used to decrypt directions and secret codewords at FBZ geocaches!

Looks like a few new recruits are gearing up for this Top Secret mission. I know there are a few others who have expressed interest in coming aboard so hopefully there will be a new squad heading out to keep us safe from those durn apes! :)

*Disclaimer: Stories here and at FBZ caches are a combination of historical conjecture, anecdote and pure fiction. Any similarity to any event, group, or person living or dead is merely coincidental. Additionally, SGTF has utilized a variety of signs/stickers as props in the FBZ geocaching series. Labels or warnings (e.g. biohazard, radioactive, etc.) which are fictitious will display some form of the SGTF/Silverback moniker; all other warning signage encountered during this or any other FBZ adventure should be respected and observed as posted.
