Each year during the summer my sister and her kids come to visit. In 2011 for Indy's birthday we did a National Treasure party with an elaborate treasure hunt. Everyone had a great time and of course I loved all the crazy detail that went into pulling off such an event. A few years went by and the kids started asking for another treasure hunt. I chose the wonderful world of Harry Potter. Each child was sorted, selected a wand and then followed clues that led them through classes such as Herbology, Rhunes, Care of Magical Creatures. (I am planning on getting the pictures soon for this and posting in more detail)
This past summer we embraced the How to Train Your Dragon craze. All the kids became vikings with the gear, a new viking name, and a dragon. After all this fun they had to complete all the training activities.
In the sandbox we created a nesting ground with dragon eggs.
I think the whole event was a success and now I just have to figure out what craziness
I will be creating next summer.
