Re:the question about hiding comms. I saw something on youtube that got me thinking. It was a internet mystery about an online video game worlds.com that is still active though it is run through expensive servers and the whole thing is ancient. It allows players to design their own worlds though and c reate groups there that are invitation only.
If the black hats are using video games as a way to pass info..maybe some of those games aren't as new as we think.
Where would most people not look for treasure? In a trash can or junk bag.
