I've talked about throwing my Journal in a time capsule and the thought sticks with me because if the written entry is about real life that means it is technically recorded history from the writers view point. There have been tons of media that has been created from compiled reports, news stories, and eye witness accounts of an event, but beyond that it is the record of the writer to be passed forward and what's inside the Journal could help the next person to open it.
Possible future people reading my Journal and finding where I buried the treasure.
