just had an idea, what if there was some contest thing like on ninja warrior on tv? if u dont know what it is look it up on utube or g4tv.com. I dont really know how it would be but just an idea to throw out there. its probably too late to start to even set up a event like this for fanime. but maybe next fanime?
Probably would have to be downgraded since I don't think all of us have the upper body strength to complete the courses
Ultimate Banzuke might be easier to do as it's indoors.
Personally I think it's best not do this due to safety issues. Fanime shouldn't be held liable for possible disasters.
