During build season, the sub-teams tend to go off and "do their own thing" and only interact when they need to (e.g. electrical, mechanical....and nobody pay attention to the "softer" sub-teams such as spirit, animation, awards, etc).
So, it's always fun to dedicate one night of non-work for a "spirit" night to have fun team awards, photo opportunities, etc just as a breather.
Just be thankful that this is indeed a limited six-week project. If it was the real world corporate stylie, we'd be doing this 24/7/365...........
