Name one natural history museum that charges $500 per ticket.
These folks are just setting up their "ministry". They are living proof that 'there's a sucker born every minute'. It's laughable.

That's to go on a five day dig. That's not your typical admission pass.
Led by people that clearly don't even know what they are digging up. It's a scam.
If I were to pay to go on an archeological dig, it certainly wouldn't be with a group that has no understanding of geology, paleontology, archeology, or anything other than theology (and a very limited understanding of even that). If people want to pay these folks to be deceived, fine, power to them. They have the right to spend their money on worthless things. It's a free country.
That wont stop me from laughing at them, however.
