^As a budding civil engineer, I can understand the difficulties the park must be facing at every turn when it comes to preserving such things. I completely understand the logistics of closing and taking down the tree house. There's no way they could have easily and cost effectively made that attraction wheel chair accessible, and the concept of having an attraction that you have to crawl across a tiny bridge to get into is just not workable these days (most of the kids are too fat anyway). As for the Apple Butter store, there were probably some ADA issues as well. Plus, it was practically a waddle and daub structure, very flamable, poor flooring, terrible inefficiency in heating in cooling, and it was pretty much in the way for new patrons trying to find Wildfire.
It does suck that so many of the small aspects are being lost, but I think come the start of the season we'll be blown away by how many little and large things have been added. I mean, remember all the fix ups we found last year? They actually got the ghost trap underneath the tree house operational again, among a million other little improvements. The theming is going to change with the times, but the character behind the park is still mostly there, and that's what's important.
ADA has been such a pain for this park though... I can't believe how little though was given to wheel chair disabilities just 30 years ago. Then again, wheel chairs were a lot smaller then, and the people usually more apt at getting around in them.
