In keeping with the focus on youth, disability rights activist Joanne O’Riordan, 19, will be Dublin’s youngest ever grand marshal. More than 250,000 people will line the streets of the capital for contributions from perennial favourites such as Wexford-based arts group Buí Bolg, Inishowen Carnival Group, and Artastic street spectacle company from Kildare, as well as visiting marching bands from the US, UK, and Brittany.
