Seattle voters have been dropping ballots into the drop box outside the Ballard Neighborhood Service Center steadily all morning, creating a loud, echoing clunk inside the building whenever the drop slot is opened or closed.

"We've gotten used to it by now," said Sonia Melchor, a customer service representative at the Service Center. "It's going to be pretty constant today. But, it's good. It lets us know the volume of people doing their duty."

Voters need to have their ballots postmarked by today, Nov. 3, or else dropped into one of the available drop boxes by 8 p.m. No postage is required for the drop boxes.

Ballard's only drop box is at the Neighborhood Service Center, located at 5604 22nd Ave. N.W.

The Department of Neighborhoods will be holding an election day open house at the Service Center from 4 p.m. to 8 p.m.

There will be refreshments, giveaways, an information booth and a chance to meet other civically minded Ballard residents.
