Macstock 2018 on July 21-22, 2018, was the fourth annual gathering of Apple faithful in McHenry, IL (near Woodstock, an hour northwest of Chicago). It had the best attendance with people from California to New York to England.
There is much that I could say, but the information is all available at https://macstockconferenceandexpo.com where you can see the schedule, the speakers, news items and much much more, including the great film "Love Notes to Newton".
If you would like to see pictures and videos that I captured while there, just go to https://www.icloud.com/sharedalbum/#B0a5aDWbra3ldw. It was so good, that many people stayed the evening afterward to continue our friendly gathering (see below).
Letha and I are going back again next year (July 27-28, 2019), and you are welcome to join us.
