Count me as one who remembers, way back when the ride was new, when the Yeti was 100% functional. Goes without saying I miss those days.
Having said all that, it's probably time we just accept the current state of the Yeti. There just doesn't seem to be any sense of urgency from Disney to fix him. For one reason or another. And maybe they don't have much motivation to do so. The ride, least from what I can tell, is still wildly popular. Doesn't seem to have been a huge dip in AK attendance, at least from what I can tell. So maybe, in their view, why spend the downtime and money to fix something that, although it needs repair, doesn't seem to be affecting sales?
Course, to folks like me, I wish they would fix him simply because I remember how awesome it was when he was working.
So it's probably time we all just accept the issue the way it is (as much as it pains me to say that). I figure, at best, they aren't going to fix him until Avatar Land is full up and operational.
