I will admit that there MIGHT NOT be "treasure" on oak island. However, my contention is that the to call the show a "hoax" as some have is unproven and the "evidence" that proponents of the "hoax" theory offer don't stand up to close inspection. I do believe that the Laginas are much more principled than to participate in such nonsense.
As I and others have pointed out that the money being spent on this search could in no way be recouped by Canadian Government grants and TV advertising. Also, considering the number of people involved in the show makes it near impossible to keep a "hoax" a secret. The "hoax" theorists on this subject remind me of the people who support the hoax theories that we never landed on the moon and 9/11 was a CIA job.
To say that "treasure" must have a monetary value is also false. Much has been learned about the history of Oak Island and many artifacts have been discovered and that in itself can be the "treasure" of history.
