It's Roborough roundabout by where Tesco is. Are you from Plymouth ?
Originally from just outside Falmouth, but mum moved to Crownhill from Newton Ferrers when Dad died (1981). Things have changed much since I was at school in Plymouth. The new road cutting the city in half for one thing. That Tesco is new, as is the roundabout. I can remember the Sperry factory about 1/2 mile from there, where you would bear right for Roborough downs, Crapstone and the cattle grid just as you hit the moor. There used to be a green, wooden hut cafe there on the left. I can't remember what it was called, just after the junction for Bickleigh.
