Okay ladies and gentlemen, if you're a true Disney fan, you know all about the Yeti. And you know why it cannot be "fixed" the way most of us would want. Here's the deal...the mountain is a separate structure, the coaster support is a separate structure, and the yeti is a separate structure. In order for the full repair to happen the mountain would have to literally be opened! Can you imagine the time and cost involved with this?
Disney just can't do it. Especially in a park that already lacks attractions. Yes, we can all admit that WDI made a major mistake somewhere with this, but they can't risk running the Yeti in full mode and having it shake the support structure of the coaster.
All of that said, the yeti is not worth discussing. It is not broken, it just "is".
