I miss doing consumer fireworks. Not allowed locally, save for sparklers, party poppers, smoke balls and other novelty fireworks. Boring, really.
So I do the Anime Expo experience. To make it more exciting, I put on a green vest. That's volunteering. Basically guide the congoers to the egress, point out the nearest restrooms, guard off-limit doors/stairs against opposite traffic, and help out in the fundraiser games (raise scholarship funds for aspiring students who need help with anime art classes) Real fun, i tell you, real fun.
They have a $30 returnable deposit to keep out troublemakers, though. That way they don't have anyone giving bad directions,
playing deaf, and pulling stunts that are generally not helpful to the Anime Expo experience.
