When teams complete the metameta, they are awarded with a diploma. The diploma has some very obvious pigpen and some less obvious morse code on it.
Pigpen: Entry sidewalk of Senator Corbett Playground use semaphore
Morse: ri is north rima mapa scma scct rima mapa scma scct njpa mapa vasc scma rict mapa scma njpa nysc scct scct mapa vanj
Going to the front of Senator Corbett Playground, the pairs of states can be treated as sempahore with Rhode Island as north. Decoding the semaphore gives the answer DEAN DEAN WE HAVE A WINNER.
