My son (Timmey001) created this puzzle device on his 3-D printer. Watching this happen is what its like the first time I saw a SpaceX rocket land after being launched into space, or perhaps when man created fire for the first time.
To find the puzzle's container is fairly simple as its inside a camo'd regular sized container at the posted coordinates. To solve the puzzle and retrieve the log, you must do a time travel back to 1976 and research one of the original computer games. It was text based and has been called by several names over the years; Avent, Adventure, or Colossal Cave. You must find a magic word that allows the player to be transported between two locations in the game. Once found, you merely use the discovered word to open the puzzle device, retrieve the cache log container and retrieve the log, sign, admire my son's ingenuity and move on!
