Never been, know lots of people that have.
THIS IS JUST AN OBSERVATION
It seems to me that mostly older people want to go see it. Even speaking specifically of people that might even believe in young earth and creationism, most of the younger generation have no interest in spending money in something they already believe. I only ever hear older members of the church talk about how "I sure would like to go see that ark" in way that makes it seem like a super strong argument for the case of Christianity or something.
I think it might be interesting to see, but I don't understand why Ken Ham spent so much money to build it.
watch Bill Nye and that guy's debates
interesting
I think I was slapping my forehead through that whole thing.
