However, the author also made a fair point about tributes to a favorite team on headstones. To wit, a "J-E-T-S Jets! Jets! Jets!" moniker on a headstone that's relevant to football fans now ... 200 years from now would cause onlookers to comment "Hmmm. Was this person in aviation?"
If we’re going to think about our headstones as a message to the future then I think confusion should be the goal. I’ve got a friend that’s an archeologist, I asked him once if they ever considered the idea that people left behind “evidence” just to confuse future historians, he said only when drinking and they all hope not.
