This is a great car show held at the Minnesota State Fairgrounds. Lots of space, lots of cars, and a loop that's easy to cruise, so the car show comes to you.
A number of the Minnesota crew attends this event every year, as it's a large show, and very local to most of us.
Out of towners are welcome and encouraged. Feel free to reach out if you're thinking of attending and need a place to stay.
