I had the opportunity to visit the project a few years ago and receive a very rare tour. At that time the Canadian Gvt. had not allowed them into the ark for a very long time.
At that time the facility was very damp/wet as the ventilation system was not active. The cots were covered in mold and if you had allergies to mould or asthma the place would likely be a death trap. I was very impressed with the structure and the layout.
I wish the Canadian Gvt. would leave them alone. They have been fighting the Gvt. in courts for decades.
They were raided on Y2K but the silly Gvt. found no guns or anything illegal and left

I'm a little over 6 feet tall and I was able to stand upright without problems.
