As far as I know, there are three Japanese sword shows, one in San Francisco, one in Florida, and the one in Chicago. When you start thinking about how far it is, remember that it's a lot closer for you to go to a show than it is for me!
There used to be one in Texas and one in New York, but the Texas one quit a number of years ago, and I haven't heard anything about the New York show in quite some time.
