Anthro NW just completed it’s 2023 convention this past weekend and still no official numbers. But I am going on what those who where there are reporting.
ANW 5 attendance: 2,151 (ANW 4: 1,498). ANW 6 will be same location Jan. 4-7, 2024.
With ANW beating their old record by more than 700 will 2023 be another year of record con attendance? Only time will tell.
