"Hi-yo, Silver!" is a famous catchphrase from the character The Lone Ranger, meaning "Let's go!" and used when he wanted to ride away quickly on his horse, Silver. The phrase was a symbol of hope and justice during the golden age of television and radio, and it has become a well-known cultural reference.
High and Silver are also clues. Finding this hide may be easier than signing the log. You will need a TOTT to retrieve the container. Signing the log is the only way to claim this as a find.
I used to have a hide in this location that would get muggled a lot. I don't think that will be a problem this time..😬
Happy hunting!
