Around a thousand motorbike enthusiasts from across the UK have gathered in Northamptonshire to support the family of Harry Dunn in their fight for answers.
A special ride left from Brackley football club in memory of the 19 year old.
Harry died following a crash with a car owned by an American woman - Anne Sacoolas - outside RAF Croughton on August 27.
Mrs Sacoolas is believed to have been driving on the wrong side of the road when she hit the teenager's motorbike.
She claimed diplomatic immunity after the incident and returned to the US, sparking an international controversy.
Since then hundreds of people have been helping to raise money for the 'Justice for Harry' campaign in a series of a special events.
That's put a smile on our face for the first time in many many weeks.. I've been crying so much but it's been tears of joy, our boy would be so proud.
In the past few weeks, detectives from Northamptonshire Police travelled to the US where they interviewed Ms Sacoolas and passed the details of the interview to the Crown Prosecution Service (CPS) for consideration.
No charges against the US suspect have been brought.
Mr Dunn's family travelled to the US last month to put pressure on the administration and President Donald Trump to get justice for their son.
However they were told by Mr Trump that Ms Sacoolas would not return to the UK.
The teenager’s parents said they had refused to meet Ms Sacoolas who was also in the White House as they met Mr Trump, as the meeting would have been "appropriate."
