1.5m tall wall by about 5 meters long. It's near the skate park so little kids may bother you but it's 100% legal! Best way to get there is get a train to bishop's stortford then head towards sworders field "town park" (opposite the multi-story). Then head to the opposite side of the field where the skate park is. The wall is slight hidden behind a small hill next to the zip wire, which you can't miss. The wall is parallel to the train tracks, so just follow that if all else fails.
Is this wall still safe to paint?
