The polling station in Arlington, Virginia used to be a bank.
The counter is still there but the tellers have been replaced by election workers, the customers replaced by voters.
It is as busy as any bustling bank branch, with a steady flow of people arriving to cast their ballots.
Early voting has been under way here since mid-September and there has been a record turnout.
Wesley MacAdam is the Assistant Registrar for Arlington County and has been overseeing elections there for 20 years.
"This is much busier than normal. 2008 was our busiest, but that has beaten that easily," he said.
Election day is still two weeks away but, nationally, around 30 million Americans have already voted either through in-person early voting or by mail-in ballots.
Mary-Ellen Buchanan said she and her family decided to vote early when she heard President Donald Trump saying he may not accept the election result.
"We wanted to make sure that our votes counted and we wanted to deposit them here in person," she said.
Joseph Lynch had similar reasons for voting early.
"This is the most important election of my entire life and I wanted to make sure my vote is counted, that's why I came out early," he said.
The pandemic is leading to a huge increase in mail-in ballots but Mr Trump has repeatedly cast doubt on the system.
He claims, without evidence, that there will be widespread voter fraud and that the election will be rigged.

There have been some isolated incidents of voting irregularities, like a case in Pennsylvania when nine ballots, seven of which were for Mr Trump, were found in a rubbish bin.
He has repeatedly cited this as evidence of fraud, but investigators say they were discarded by mistake.
There are fears that there could be unrest at polling stations with Mr Trump encouraging his supporters to become "election poll watchers" to keep an eye out for suspicious activity.
Experts insist however that actual cases of voter fraud in the US are extremely low.
Michael Waldman is the president of the Brennan Centre for Justice at New York University Law School.
"Donald Trump says, voting by mail is rigged but you've got Republican and Democratic officials quietly working in the states to make sure the system works," he said.
"Many states have changed their rules in the middle of all the drama and tumult so that vote by mail will be better this year and votes will be counted," he added.
There are concerns that Mr Trump may refuse to accept the election result and the outcome could be challenged in the courts.
Several legal disputes have already sprung up in individual states.
There have been court battles over voting deadlines and over what makes a vote invalid like using the wrong colour pen, a mismatched signature, incorrect ID or sending in what's known as a "naked ballot".
Voters in certain states have to use two separate envelopes for their mail-in ballot otherwise it will be deemed to be a "naked ballot" and the vote won't be counted.
There are also concerns about political interference in the postal service and a shortage of ballot drop-off boxes in some areas.
All the uncertainty means many Americans just want to get out to vote in-person as early as they can.
In Virginia, the polling station may not be a bank anymore but early voters, like John Moore, felt they were making an important investment of a different kind.
"This is the most important election of my lifetime and my kids' lifetime, we need to vote that guy out of office," he said.
