Authorities were wondering what 11-22 (among the other numbers) stood for, and seemed to feel, back then, that another 9-11-01style attack might occur on 9-22-01. Authorities were also wondering if the numbers they found were telephone numbers, but seemed to rule that out as a possibility. Some time later it occurred to me to check the calendar to see if 11-22 is Thanksgiving's date this year. It is.
I seem to be the only one who remembers the reports of puzzlement about the numbers 11 and 22. Maybe I dreamt it up.
