I used to live there as a kid and played on the pitches against the Grammar School. When my daughter was playing there season before last it took me a couple of goes to find it. The route you take walking as a kid is nowhere near the route you go by car
Don't forget your camera, you can see the end of the world up there on a clear day, and if it's foggy the match will be off, it's not fog, it's low clouds
Fairly sure the one on Glen Rd is an astroturf pitch for the grammar school.
