Travellers (also known as itinerants and tinkers, though
	these names can be seen as offensive) are people in Ireland
	who have traditionally lived "on the road", typically in
	caravans moving from place to place.  In many ways they
	can be seen as a separate ethnic group and they are often
	subject to ethnic prejudices and discrimination.
