Very little of the Ark is original now. At most, it's maybe 25 years old. The mechanism and "look" is still pretty classic, but again, not really original (well, the mechanism IS original).
I loved Noah's Ark though, massive amounts of fun... Even trying to get a toddling Maxi-Minor_Furie through it. I adore attractions like this which offer something completely different to anything modern parks ever deem we're worthy of. New space age play park or water splash zone for the kids? Give them a wobbly stair and a farting cow and they'll be much happier
I will say I prefer this idea to demolition though. At least this way the ride is still there. Even as a walkthrough with the "contraptions" gone, it's better than being chainsawed. Maybe in the future it could be revived, maybe not, but it's better to have it as "something" than not have it at all.
So yeah, sad news it's not going to live on as one of the most fun attractions in the country any more, but good news it's still going to live on...
