Very cool and interesting photos. We were at WDW twice over the summer, and I was shocked at how much things changed within a matter of weeks. I know it would be virtually impossible to prevent, but I'm surprised at how "accessible" the progress is - between the train and Dumbo, it's easier than I would've expected to get a peek. We have some progressive photos of Everest's growth and Wizarding World over at Universal, and it's neat to have them to compare.
Of course, maybe that will change with scaffolding and stuff when the construction begins on recognizable landmarks, but I hope not - I love seeing the progress!!
