I can't recall seeing any Disney-inspired plates here in Michigan. I guess the field is wide open, Michiganders! However, I see oodles of Disney antenna toppers.
We have University of Michigan "affinity" plates (Go Blue!) When in Ann Arbor....
Staff member Chad has Michigan State plates. For the sake of harmony, we leave our team loyalties in the parking lot.
Lacking an antenna, we have a Disney antenna topper displayed inside the windshield, sort of like a dashboard ornament.
