Y'all might look at me funny for this, but team 180: S.P.A.M. Even if their robot isn't the exact same shade of blue and red as their shirts and capes, there is something about an entire section of the Colonial Center going "S-P-A-M! SPAM! SPAM! SPAM!" that definitely turns heads! (Heck, my first FRC regional was five years ago now, and there are two chants that I still remember from it: theirs and ComBBAT's*.)
For the total package, though, I've long been fond of the way 1902 manages to tie together everything. From the shirts to the robot to the website to the pit, they're always able to tie it all together. Every season, they refine it just a bit--and every season, I'm stuck adding another item to my Things I Should Show The Team list. Gee, thanks 1902!
*On that subject, WHO DAT BBAT?
