Found this in a cache. Wouldn't let me choose "found" so just using the next one "grabbed it". I was going to take it to South Dakota with me, but it looks like it would rather get to the headquarters here in Washington.. so will try to do that instead!
TFTCoin!
EDIT: Just looked at the log and it has actually made it to the HQ! So I will for sure take it with me on a trip to see Mt. Rushmore or Crazy Horse Monument or somewhere in the Black Hills of South Dakota!
