It sounds impossible — canceling the world’s biggest one-day car event.

But canceling it is what the cities on America’s signature cruising highway hope to do.

On Monday, Birmingham’s leaders voted 7-0 for a resolution asking to cancel the Woodward Dream Cruise, set for Aug. 15. On Tuesday night, Huntington Woods followed suit, 5-0. Ferndale City Council? Expect a vote next week.

All nine of the cities involved are weighing in against allowing any official activities in the annual car craziness that draws fans from Australia, Europe and across the U.S. and Canada.

It wasn’t an easy decision, said Michael Lary, events manager for the city of Ferndale. He’s also unpaid president of the nonprofit board that stages the Dream Cruise.

“There are enormous fans of this event. They’re passionate about their cars. Believe me, I’m not happy,” Lary said.

“We’re making a decision for hundreds of thousands of people. But we’re doing it for the right reason” — that is, to protect public health, he said.

But speaking of public, Woodward is a public highway. The Dream Cruise has always been free — to drive in it or watch it. That means, cancellation or no, people will come to cruise.

“We get that,” Lary said, adding that no one will be ticketed just for showing up in a cool car.
