For reporters trying to cover the opening months of Hillary Rodham Clinton's second presidential campaign, Waterloo, Iowa might be her Waterloo.

On Monday night the Clinton camp held a private campaign party at the home of a wealthy pharmacist in the central Iowa town – a longtime Democratic Party figure – and Daily Mail Online was the only media outlet to make it to the address.

Other press outlets can't be faulted, however: Clinton's aides kept the existence of the party a secret, leaving it off of the schedule circulated to reporters who cover her events in a rotating 'pool.'

Daily Mail Online only found the location after trailing the candidate's motorcade at a distance for an 85 miles trek, at speeds reaching 95 mph.

SCENE OF THE DODGE: Hillary Clinton's motorcade cruised from Mason City, Iowa to Waterloo, Iowa at speeds topping 95 MPH, arriving at a secret party hosted by Bob and Cheryl Greenwood in their palatial home

Bob Greenwood, pictured with his wife Cheryl, is a pharmacist who unsuccessfully ran for the Iowa state legislature in 2012 and served three terms on the Waterloo, Iowa city council. The Greenwoods hosted a Monday night party for Hillary Clinton that was hidden from reporters

Clinton's motorcade arrived at the 5,000-square-foot Waterloo home of Bob and Cheryl Greenwood at 6:30 pm, with five escort vehicles accompanying her maroon minivan.

The ordinary Chrysler rental was a surprising stand-in for Scooby, the black custom conversion van that had previously ferried Hillary through Iowa and New Hampshire.

The Greenwoods' neighbors were expecting traffic in their upscale cul-de-sac subdivision.

'This has been in the works for weeks,' one elderly attendee said as she walked down Muirfield Street. 'We've been counting the days.'

She followed two middle school-age children at a distance up the tree-swept street. They carried copies of books for Clinton to autograph.

It's a scene that might have done Clinton a world of good to have preserved on video: cars lining up on a neighbor's lawn like a summer concert parking lot, kids in their Sunday Best on a Monday and locals arriving with 'Hillary 2016' buttons already pinned and stickers neatly pressed on.

A middle-aged woman said as she left and walked toward a nearby church parking lot that there were 'about 75 people' inside. 'We had a blast. A grand time,' she crowed. 'You should have seen it!'

Almost no one did. The press corps wasn't welcome.

An earlier afternoon event in Mason City, Iowa, managed to attract a swarm of photographers and cable news correspondents who grabbed images of the arriving motorcade even though the location was a tightly held secret.

'Hillary will attend a grassroots-organizing event at a Mason City home,' the campaign's press schedule read, noting its location only as 'Mason City, IA.'

It was the only item on Clinton's agenda – officially. Reporters shouted questions as Clinton left, but she acknowledged no one.

In Waterloo, they didn't have the chance to be actively ignored.

'It's maddening,' a print journalist who was in Mason City for Monday's earlier event said in the evening, asking to remain anonymous for the sake of her career.

'We can't do our job if the Clinton campaign freezes us out and tells us there aren't any more events for the day – and then they race to Waterloo for an event. Don't they understand that they need us as much as we need them?'

There is no record of what she discussed Monday night. Bob Greenwood himself did not respond to an email seeking comment.

Neither did the Clinton campaign. Daily Mail Online received a form-letter reply instead.

'Due to the large volume of requests we receive please allow 3-5 businessdays for a response,' the message read.

Greenwood is a party loyalist – a former three-term Waterloo city councilman and a failed 2012 candidate for the state legislature who in 2013 received the American Pharmacists Association's highest award for 'government and legislative services.'

Greenwood is also the president-elect of the Iowa Pharmacy Association.

Clinton is acquiring a reputation for skirting reporters' questions. An online counter published by The Washington Post has counted the minutes – more than 39,300 of them – since she has fielded a question from a journalist.

As reporters get anxious, voters miss opportunities to hear her weigh in on Iran's nuclear ambitions, the Trans-Pacific Partnership trade proposal, and her own scandals involving alleged conflict-of-interest problems at the state department and a private email server where she secretly conducted all her electronic communications while in the Obama administration.

On Tuesday she has a small-business roundtable event scheduled in Cedar Falls, Iowa – a manicured happening of the vintage she has served to journalists before. Pre-selected Iowans will ask her pre-cleared questions on pre-arranged topics.

The maroon Scooby van will deliver Clinton on Tuesday morning to Bike Tech – a Cedar Falls cycling shop – for the staged affair.

Pre-approved journalists, including Daily Mail Online, may attend. But if Clinton has another secret event up her sleeve Tuesday afternoon, the world may never know.

Few reporters will talk about their frustrations with covering Clinton. One other, a cable television news correspondent who, like the first, requested anonymity, mused on what may be in store for Team Hillary.

'Maybe by this point next year Hillary's people will be clamoring for us to interview her as Elizabeth Warren and Martin O'Malley make mincemeat out of her,' the same journalist observed. 'But for now dodging the press just comes off as arrogant and imperial. Which is not the model she ought to be trying to emulate.'

'I mean, really: If you hold a campaign party and there are 100 of us flying in to Iowa to cover you, the least you can do is tell us the event exists. We don't expect you to feed us or mix us martinis. Just don't make this presidential campaign marathon any harder or more idiotic than it needs to be.'
