More than 300 trucks will rumble and roar into Camden at the end of this month for the annual Haulin' the Hume event.
The charity initiative brings together truck drivers from across the state in support of children's autism charity, Aspect.
This is the first time the event will kick off in Camden making it extra special for long-time participant and Bringelly local Michael Cefai.
"I usually join up with the Haulin' the Hume when they reach Macarthur rather than starting at Richmond, so it's nice to have it start at home," he said.
"I have participated each year to support the kids out there who need it.
"My son is autistic so we do it to raise some funds and awareness and support other kids like him."
Mr Cefai comes from a long line of truckies and has a particular passion for vintage vehicles.
"The old folks did it tough back in the day so it's nice to drive the older trucks and see how they did back then," he said.
"We have all the luxuries now but there's nothing like the sound of the old trucks."
This year's event will also commemorate the 40th anniversary of the Razorback Blockade.
In 1979, truck drivers appalled with their working conditions decided enough was enough.
The men blocked the old Hume Highway at Razorback by parking their trucks across the road.
One of them was Macarthur local Spencer Watling.
He remembers the feeling of desperation that led to the blockade.
"We had tried everything to get the government to do something about the way we were being treated," he said.
"We had gone to everyone we could think of. This was the last resort.
"We thought we would end up in jail but we were surprised about the support we had from everyone."
The blockade ended after several days when the government agreed to scrap the tax preventing drivers from earning a living.
Haulin' the Hume organiser Bruce Gunter said it was important to recognise the efforts of these men.
"We are starting at the Camden Bicentennial Equestrian Park this year because it's an ideal location right at the bottom of Razorback," he said.
"We'll do a tribute drive to the memorial and then back down to Camden on Friday afternoon before we head off for the main event on Saturday."
He encouraged residents to come out to the event.
"It's visually spectacular," Mr Gunter said.
"People love seeing the old trucks rumble up the hill."
Trucks will leave Camden at 6.30am on March 30.
