Yes, the Irish Travellers are different from the Roma, but similar in that both communities tend to maintain their itinerant lifestyle by schnookering city folk, which they define as people living in any settled community of three or four houses. In the US they often pose as laborers-for-hire for small contracting jobs. My Dad got hit by a paving scam where they took some money to resurface the paved access road at our farm. They laid asphalt all right, but of course incompetently and in a half-assed manner, then ran off.
