Here is an article from the all about Ann Arbor website, ClickOnDetroit.com. The Guild had their jurying recently at their offices in Kerrytown, heart of Ann Arbor, and they invited a reporter to attend.
To the general public the Ann Arbor Art Fairs look pretty much random: lots or artists, lots of people, vendors and distractions everywhere. Yes, the event draws over 200,000 attendees every year, so that is what it does look like to an outsider.
You and I know that you applied to these shows probably six months ago, you agonized over your work and then the application and the jury images (!), lots of stress. Of course besides your labor the organizations hosting the events have year round staff and they work on it every day of the year.
But maybe you're new to the shows and you'll find this outsider's perspective interesting: https://www.clickondetroit.com/all-about-ann-arbor/takeaways-from-the-ann-arbor-summer-art-fair-selection-process
