Could be gypsies, but there are also “Irish travellers”.
BYW, Irish Travellers have been running the driveway repaving scam in the U.S., especially in the Boston area.
Irish Travelers call themselves “Gypsies.”
South Florida periodically gets a Scottish version of the travelers, the Terrible Williamsons. They swarm over a city with all sorts of roofing and driveway scams and all types of theft jump up until they move on. I think the Irish and Scot travelers headquarter in the Carolinas somewhere. We get actual Gypsies, too, on occasion, but they come in smaller groups.
