That's a great way to celebrate! You look like you could easily have the party yard thing going there. Very nice.
I would love some palm trees in my yard, but they don't do so well around here. I settle for dragging out a fake one for the inside of the house when I "summer-ize" the house. I've been waiting for us to see a hint of spring, so I can put the winter stuff away and switch over, but it's been to cool and gloomy to be feeling summer stuff. Finally we're getting sun and warm temperatures, so this could be the weekend to dust off the old palm tree!

Palm trees are something I really do miss from my St. Pete days.
I celebrated Earth Day in my classroom, too, by doing acrostics and an animal theme to tie in with Animal Kingdom's birthday celebration. Each kid chose an animal, drew a picture, and wrote a word bubble with the animal telling humans to help take care of their habitat. They had fun with it, and even though they never knew they were having a Disney day, I was enjoying the fact that I could at least be doing something halfway related to what all was going on in Animal Kingdom yesterday. I wish I could have been there. I'll put that on my list of special days to celebrate in WDW. I'm chipping away at that, and I'd be happy to have any excuse and add any special day to the list to plan a future trip.
Some of the resorts planted new trees yesterday, too. I'm going to see if I can find Pop's new tree(s) when we go in June.
I'm with you on the MNSSHP being worth it. Every Diser needs to go once, because it's so different than just a regular evening at the park. Very neatly themed.
