A Castleblayney estate agent is absailing 190 feet in aid of the Ronald McDonald House.
John O'Brien is one of five DNG auctioneers taking on the Smithfield Tower of Terror challenge tomorrow along with hundreds of other fundraisers.
While representing his organisation, John has a special connection to the charity as his friend's family have availed of the service when their daughter was ill.
The Ronald McDonald House provides accommodation for families while their children are receiving treatment at Crumlin Children's Hospital.
John says he doesn't mind the height when he knows it's for a good cause.
