Each year Camp follows a theme which is used during devotions, the banquet, for the booklet and naming tents, etc. In the past it’s been: The Simpsons, The Incredibles, Big Brother, Finding Nemo, James Bond, Narnia to name just a few.
The theme for this year is: Up! (the Disney/Pixar film)
That leaves you plenty of time to think about what you’ll be wearing to the Camp Banquet (balloons?, adventurer outfit?). If you need a little inspiration, take a look at the official Up! website or WikiPedia for everything you could wish to know.
