On average, the first Thursday — typically the first day of the Great Minnesota Get-Together — draws about 105,403 people, the "lowest" number of daily visitors during the fair's 12-day run, according to attendance figures from the past five years.
Compare that to 229,331: the highest number of daily visitors, on average, for the last Saturday of the fair. In 2016, the fair even set a new attendance record, with 260,374 on its last Saturday.
Now wait a sec, you say. What if I can't go to the fair on the first day because I have to work?
Your next-best bet is to plan ahead and take a personal day on either Tuesday or Wednesday. On average, each of those days draws just under 116,000 visitors.
