A big black car swooped along Main Street in Front Royal.
The crowds shouted ready to see the King and Queen - except it was Foreign Secretary Yvette Cooper who hopped out, accompanied by bluegrass music.

There’s warm sunshine in the Shenandoah Valley, with the crowds in Front Royal warming up their welcome.
There’s a focus on Appalachian traditions, including clog dancers. They’re rehearsing nearby, the sound competing with a police helicopter circling above.

Organisers have been going round handing out US and UK flags to wave. It's a Virginian town of 15,000 people - with shop names like Loose Cow Mercantile and Weasel Creek Outfitters.
When the King and Queen arrive, they won't be the first famous visitors.
Bing Crosby sang here once for a fundraiser in 1948. And that's never been forgotten. There was a baseball ground named after him.
Maybe if the royal couple returned in a few years, the shop that is now Proctor Biggs Feed Mill might have been renamed Proctor Biggs Feed Camilla.
Image source, ReutersWhile at the Front Royal block party, the King and Queen will also be meeting with local charities that support survivors of domestic violence and first responders, as well as with scout groups and the Virginia State Little League team.
The royal couple will also view an agricultural display, including locally bred Welsh-origin Kerry Hill sheep, beekeepers, flower farmers, and aspiring young farmers.
The region's Scottish and Irish heritage will also be honoured with traditional Appalachian clog dancing and the aforementioned bluegrass music.

Image source, ReutersThe King and Queen are in Virginia on this last day of their four-day state visit.
And they're going to see something they haven't seen so far - regular people.
All the events in Washington DC and New York were highly controlled in terms of who they met and what they were shown, in settings that were surrounded by an intense security presence.
They were events in a sealed box.
But now we're in Front Royal, small town America, and it looks like half the town has turned out to wait to see the royal visitors.
It all feels much more relaxing, and there's bluegrass music playing to greet them.
Crowds are already awaiting the King and Queen at their next stop - the town of Front Royal in Virginia.
Here the royals will attend a block party to celebrate the America's 250th anniversary.

It's a long tradition for British royalty to visit the Virginia cemetery, particularly the site's Tomb of the Unknown Soldier.
The monument, which was built in 1921, honours unidentified American soldiers lost in war.
King George VI visited in 1939 with his wife, the Queen Mother, laying a wreath on the tomb.
Their daughter, the late Queen Elizabeth II, visited the site multiple times during her reign, including in 1957, 1976, and 1991.
In 1985, King Charles - who was then the Prince of Wales - visited the Arlington National Cemetery with his then-wife Princess Diana.
And in 2013, Prince Harry visited the site, where he walked through the rows of gravestones.

There was surely a sigh of relief from the King and Queen as they departed the White House after the official goodbye.
This has played just as Buckingham Palace and the UK government had hoped - the King had his say in that speech to Congress. He made his point without obviously upsetting his host.
The president’s love for the Royal Family seems undiminished.
As the King and Queen said their goodbyes to their hosts, the Queen and first lady could be seen talking, with the Queen pointing out something on her outfit.
She was showing Melania Trump the Tiffany brooch she was wearing. It had been a gift from the first lady during the Trumps' visit to the UK last September.

Image source, ReutersThe King and Queen's trip to Arlington National Cemetery follows shortly after their formal farewell with US President Donald Trump.
The official goodbye showed the different approaches of the president and the King.
Donald Trump was happy to chat in front of the camera. The King seemed less enchanted.
When the King was asked for a favourite moment from the trip by reporters - there was no clear reply. Just a smile - he was not going to be drawn into any public exchanges.
The visit to Arlington Cemetery - where he is at the moment - will be deeply meaningful for the King. As head of the UK Armed Forces, honouring those who’ve served is built into just about every state visit he embarks on.
Much of this trip has mirrored elements of trips to the US undertaken by the King’s mother - the late Queen Elizabeth II. When he laid a wreath at the Tomb of the Unknown Soldier today, he was walking in the footsteps of his mother who did the same during her first state visit to the US in 1957.
Image source, ReutersAfter a brief pause, the royals then move away from the monument.
They pass a small crowd of onlookers, and up some stairs into a building.
US service members march in front of the building, carrying assorted flags as a drumbeat plays.

The Queen then walks up to stand next to him. She's handed some flowers which she also lays at the foot of the monument.

A long motorcade could be seen driving down the road to the cemetery.

Here at Arlington National Cemetery, the royals will lay a wreath and posy at the Tomb of the Unknown Soldier - to honour the US and UK’s military partnership.
They’ll also view the Canadian Cross of Sacrifice and meet groups of serving military personnel from the UK, Canada, Australia and New Zealand.

They'll be here shortly - as they conclude their final day of their four-day state visit.
Security has tightened as Secret Service officers and dogs have been going around sniffing cars in the area.
I have just spoken to someone who was inside the cemetery, who says that many visitors are not aware that the King and Queen will be there.
Their visit is expected to include a wreath-laying ceremony honouring fallen service members.
The King and Queen are expected to arrive there imminently - watch live at the top of the page.
Image source, ReutersShortly after the car drives off, Donald Trump tells the gathered press: "Great people."
"We need more people like that in our country," he says.
The US president thanks the press, and then he and the first lady turn around and go back inside the building.
