OMG - I love this thread!
So many memories coming back to me, and I am realizing that I do have experienced a lot even though I only have been coming to WDW since 2005.
While I'm looking forward to Avatarland, I'm still a bit sad that Camp Minnie Mickey is no longer around. Especially since it was one of the easier locations to find other animal characters (Thumper and Miss Bunny from Bambi). And ever since that got demolished and the dance party at Dinoland is gone. Those two only show up randomly.
