@Notmath1 - I think the numbering attending Unifieds in Chicago is easily more than 500 and may push 1,000. I think I could easily count 100 kids per floor mid-day in the Palmer House on three or more floors where there were audition rooms. That’s 300 right there and, of course, that would in no way represent all the students attending. Hence, by my extremely crude estimation, the number is some multiple of 300, say 2-3 (based on an estimate that only about 1/3 to 1/2 of the students are out and about in the hallways at any given moment in time), which gets you to a range of at least 600-900.
