Thanks for bringing this up.
I'll be sure to add this topic to our team itinerary.
Namely, "Littering via throwing paper airplanes in the Dome does not align with Team 1678's public image. Please focus your energy and enthusiasm towards the competition and your roles on the the travel team."
Also, the paper airplanes can be disruptive to matches. A ref needed to remove this airplane from the field before
Einstein Finals Match 2.
Although not every team will, I'm sure many teams could be proactive in addressing this behavior.
Now, it doesn't help when a CMP speaker tells your kids to throw them
