Hundreds of people were spotted standing on bridges along the Buckinghamshire stretch of the M40 in the early hours of June 8.
But for what reason?
The get-together is in tribute to the late Hairy Bikers star, Dave Myers, who passed away in February this year at 66 from cancer.
In honour of the TV chef, roughly 20,000 people will embark on a huge cross-country motorcycle ride from London to his hometown of Barrow-in-Furness in Cumbria.
The journey is roughly 300 miles, and will take close to six hours to complete.
And those in South Bucks noticed many people standing along the country’s motorway bridges, waving at the riders when they passed through the county.
Dave’s onscreen partner, Si King, spoke to BBC Breakfast about the event.
He said: “It’s pretty amazing.
“Everybody’s got that lovely Dave sartorial elegance about them, ie dodgy shirt.
“Some of them have had them specially printed, it’s remarkable.
“I mean, you wouldn’t buy a second-hand car from them, would you?”
““It’s a celebration of my best friend that we’ve lost. And, yeah, it is, it’s very emotional.
“You never know how these things are going to impact you, you know, it is a celebration of Dave’s life.
“That’s why we’re here because he was so irritatingly positive all of the time. And we love him and that’s why we’re here.”
When all the bikers arrive in the North West later today [June 8], a music concert and a service of remembrance will take place.
The day will raise funds for cancer charities and children’s charity the NSPCC.
Myers’s widow Lili Myers told BBC Breakfast: “We have people coming from all over the country.
“We have people coming from Texas, from Malaysia, from all over Europe.
“Oh, it’s endearing. It just helps me go through my process of grief. Because it just makes me feel that I’m not on my own with all this.
“He always cooked, that was his territory. I wasn’t allowed in the kitchen, just to clean the kitchen and, I tell you, he would cook for an hour, I will clean for two. He knew how to create a moment. That was his forte.”
Jason Woodcock, who organised the event, added: “I went to see him the day before he passed.
“Lili asked me for a couple of bikes together for his funeral, which I did. Some of the guys that are here today were there as well.
“They got to the funeral, had a few beers as you would do.
“And then the idea came up during the conversation of let’s do a memorial ride.”
The day will raise funds for cancer charities and children’s charity the NSPCC.
