As I have said before.. It is subject to debate whether Dan and Fred have 'wasted their lives pursuing a treasure that does not exist' or have had 'full and meaning full lives pursuing their dream'... With the laginas I get the feeling this has always been Rick's dream and Little brother Marty has just been dragged along for the ride. Initally to finace his big brothers dream but also to bring th business sense to turn the whole thing into a reality tv show and make a profit on the endeavor or at least mitigate the losses...
The question though can be legitimately asked if they still believe that treasure is there? (or has ever been there?). They present the Descendants claim of the original finders of the pit taking the treasure but never investigate it. Does this mean they do not believe the sisters or that they do believe them and are just spinning on the show to make some more money. It cannot be both. No one can really believe that the treasure hiders hid a motherload of treasure at 170+ foot and then put three chests at 20 foot to make anyone digging the hole think hey this must be the treasure so I will give up.
If the sisters story is to be believed (which I personally find credible and a plausible explanation for the whole legend) then digging further is pointless. We know that they know about the alleged coins and gold nugget that descendants also have and is claimed from the original finders, in that the blockhouse blog article tells us the Laginas know this story. The article tells us they made the descendants sign a non disclosure agreement about these items previously (which must mean the Laginas paid them). Why have they never mentioned them or seek to show us them. That is dishonest on their part because it would make selling their TV show much more difficult.

Even if they believe these people are all lying (or have been deceived themselves) they should of investigated the story and shared it.
I am happy they are investigating a story that has fascinated me since childhood but am disappointed that they are not trying to really answer the mystery now they are simply seeking to make money selling the show and spinning it off for a 5th season... We also know that 5 seasons were approved (sasquash posted about this a long time ago) much earlier which also suggests they never wanted to find treasure before they had milked all 5 seasons.
I love the legend but do not like being lied too...
