I'll call 217: Mentoring many FLL teams, running a huge FLL Tournament, fulfilling Dean's homework every year, hosting the Ford Robotics Invitational (aka Sweet Repeat), co-hosting the Kettering Kickoff event, Mentoring other teams, cooperating on design with 229, the FIRST demonstration at the YES expo on the NFL's Ford Field, successfully leading students into engineering and design, and of course, building an unbelievable robot year after year.
That's all I could think of off the top of my head. I've never actually had the pleasure of reading their chairman's submission
However, that's not to undermine the creativity and success of every other deserving team out there: CyberBlue's international cooperation program, Miss Daisy's Team-in-a-box, 66 bringing younger students to competitions, and so many more.
And yes, my call might just be slightly biased.
