we have been on holiday ( a short one lol) & we have been to Kentucky TN too see the "ARC" & I have to say it was fascinating! I won't spoil it for others but I will tell you one of things that we learned while we were there. Craftsmanship was amazing & the detail so fine. They are made from a 3D printer on a large scale & made out of Styrofoam & then they go from there. Some of the animals created with fur are put together with a needle & thread using one single strand @ a time. That's more patience then I have with a needle & thread lol.
Sounds like you had a good time!
