A special weekend-long celebration of the Road Roller Association’s 40th anniversary will be held in Halifax.
The group was formed by Lyndon and Barbara Shearman and now boasts 400 members from across the UK.
The weekend will include visits to Marshall’s quarry, Rigg’s garden centre and the Calderdale Industrial Museum.
There will also be a talk by Lyndon Shearman after the organisation’s AGM at the White Swan Hotel in Halifax town centre.
He said: “Me and my wife got a meeting together with like-minded people in our front room and had a chat about forming it.
“We held our first official meeting at the Golden Lion Hotel in West End and we wanted to return to the town where it was formed.
“We provide training so that people know how to use the equipment and we publish a number of books on road making and rolling.
“We’re expecting 60 or more people to attend and we’re really looking forward to it.
“Halifax has lots of cultural and historical points of interest that our members will be visiting.
“We’re sure everybody will have a wonderful time.”
