Whenever I go to WDW, I always have one big highlight each trip. 

  So, this time, it was something I saw at Animal Kingdom.  
Now, I know that a number of people aren't big fans of Rafiki's Planet Watch, but I always liked the little train ride that goes there, and I find that general area to be peaceful with the petting zoo and all, and not as hectic as the rest of the park.
Anyway, when I entered Conservation Station, I walked over to the veterinary treatment room (the big picture window, where you can see inside) and saw something amazing!  There was a 300-pound, female Bengal tiger on the operating table!!  
 
 
  (She was sedated, and there were vets and technicians all around her.)  I was only about 12 feet away from her (again, shielded by the window).  They were trying to mend her ear, because she had been in a fight with another tiger and was injured.  By the way, you should have seen the size of her large paws!! Yikes!  
She was a gorgeous animal, and I was thrilled to get such an up-close look at her and watch the vets work their magic.  This was one of the very best experiences I have had in all of my visits to WDW over the years!
