text: No worries. Looking at the aerial imagery, I think it was probably all the neatly laid out bits of planting in the pentagon to the South West of my note, and the bits surrounding that, but the paths outside that area were still accessible. In short it probably needs a re-survey. I think there were possibly also more paths SE and NW from the oval shape the note is within, I don't think we had to backtrack all the way to the NE corner to take another route, but they are hidden by trees in the satellite images if they existed.
