I presume many attendees are not single persons, so they could be grouped by group. The student population, well there I don't know as they would be grouped closely together at school frequently.
I think I should wait, my guesses likely will be wrong anyway. As noted, by August, "things" may be rather different.
I recall in late March going to Kroger and the place was almost stripped by panic buying. I had been there two days before and things were "OK". I started worrying about the food distribution system just failing, it didn't obviously.
If I could have been promised the situation of TODAY on March 25th, I would have taken it in a second. We're better off now than I expected.
