A lot like portsmouth, which has an "Out of city" signpost at every junction.
Back on topic, I go to Shirley a fair bit, living just down the road in Nursling, and sure, its full of Poles. They seem fine to me, and most of them seem to be working. It must be a bit of a hotspot given the number of Polish shops along there, cant see a problem myself. If they come here to work and pay their way, then fair play to them.
