I have not brought it up much on this blog before, but there is a great event that comes up every year in July. In sunny and hot Kansas City, Missouri is the quintessential Apple II meeting, KansasFest. I highly recommend it for all who want to experience a group of people who are some of the most knowledgable Apple II folks in the world. The keynote speaker this year is John Romero, noted game designer, who cut his teeth programming on the Apple II way back when.
