Re: senior project idea... Aikido Demonstration?
My dojo participated in a senior project event last year. The senior that put it together invited several schools to participate in the demo and as part of his overal project, did a history for each of the martial arts presented. Everything he did, from the invites, to communciation, advertising, etc, was documented. We had aikido, whushu, karate, kali/escrima and some other home grown system perform. Afterwards, there was a pizza party for all participants. It was held at the High School gym. Not sure what kind of costs were involved.
Good luck ...
