It is the annual convention of the Pyrotechnics Guild International, Inc. We have seminars, workshops, product demos, sales of chemicals, pyro-related items, etc. Main thrust is to let amateur fireworkers compete in all the different types of homemade fireworks (shells, mines, comets, etc). Within these types are classes based on size and difficulty of making the items and getting them to perform as they should. Many people come with their families just to buy and shoot consumer fireworks or watch the big shows each night culminating with the Grand Public Display on Friday. I hosted this convention twice in the '80's, but now we do not have enough motel rooms. More info at
