ANN ARBOR, MI - Marc Murawski believes he might have just created the world's largest Donald Trump sign.

"If there's a bigger sign out there, I don't know where it is," he said in a phone interview on Monday, Oct. 31.

The 49-year-old consulting engineer from Ann Arbor Township spent last Friday and Saturday using a tractor to mow the Republican presidential candidate's last name into a large field a few miles northwest of downtown Ann Arbor. He went up in his plane on Sunday and took photos of it.

"I like to think it's the largest one in the world or the history of the universe, but I might be wrong," he said. "If it isn't, I'll have to make it bigger."

Murawski said the letters are about 120 feet tall and they span almost 700 feet, making the sign somewhere shy of 84,000 square feet.

He notes that's bigger than a similar Trump sign measuring 58,000 square feet that's mowed into a lawn in Lapeer County.

Murawski, a pilot, said he designed his sign so someone with 20/40 vision could see it from 54,000 feet up in the air.

"So all air traffic over Ann Arbor will be able to read it," he said, adding there's a lot of cross-country plane travel over Michigan, so he suspects a lot of people will be seeing it between now and Nov. 8.

Murawski said a good friend of his allowed him to use the field. He said the owner doesn't want to share the exact location for fear of vandalism.

What inspired Murawski to make such a large Trump sign?

"I've been putting up signs and campaigning for him, and yard signs tend to get stolen pretty quickly from what I've seen," said Murawski, a University of Michigan graduate. "So I wanted to do something that couldn't be removed easily, and this will be the best exposure I can get."

Murawski said he's supporting Trump because he thinks the businessman is the country's last hope to stop Hillary Clinton from becoming president.

Murawski describes himself as an independent with Libertarian views. He said he supported Ross Perot for president in 1992, but unfortunately that just helped launch what he calls the Clinton dynasty.

He said he voted for Barack Obama eight years ago with hope for change, but he has been disappointed. He also thinks the Republican Party has been an embarrassment this election, particularly because of its treatment of Trump.

"I think Trump has energized a lot of people who are fed up with the status quo and want an outsider coming in to clean it up," Murawski said.

Trump is continuing to campaign in Michigan, with stops planned for Monday in Grand Rapids and Warren.

Chelsea Clinton, daughter of the former secretary of state, and Bellamy Young, an actress known for her role as first lady and Sen. Mellie Grant in the ABC television show "Scandal," both campaigned in Michigan for Clinton over the weekend.
