Hi Jfoxy found this tidbit of info on a rootschat site
In the period we're talking about, there weren't any authority-designated camping sites: the Gypsies would pull onto any spare wasteland they could find - usually the land that no-one else wanted to live on or do anything with.
If they found a likely spot, they would often return to it regularly year after year. More elderly family members might even stay at that place all year round, while their children were on the road. One such place in and around Birkenhead was at Green Lane, Tranmere. I understand it was an abandoned brickworks.
