One landed right in front of us while placing a stack on Einstein Semis...
For how awesome Einstein is and how well done everything looks and feels. Seeing a bunch of trash lying around really kills it. I also noticed when leaving the stands later that because of the airplanes (a.k.a. trash) people felt compelled to leave their own trash (food, drinks, candy wrappers, etc.) on the ground as well. Its embarrassing.
Thank you to the mentors who made sure your teams policed their areas and cleaned up after themselves.
