Many Travellers are breeders of dogs such as greyhounds or lurchers and have a long-standing interest in horse trading. The main fairs associated with them are held annually at Ballinasloe (County Galway), Puck Fair (County Kerry), Ballabuidhe Horse Fair (County Cork), the twice yearly Smithfield Horse Fair (Dublin inner city) and Appleby (England). They are often involved in dealing scrap metals, e.g., 60% of the raw material for Irish steel is sourced from scrap metal, approximately 50% (75,000 metric tonnes) segregated by the community at a value of more than £1.5 million. Such percentages for more valuable non-ferrous metals may be significantly greater.
