Instead of following the street, I immediately turned right onto another footpath. After passing the garden of a bungalow on my left, the path went half-left across a meadow. It then continued across a corner of an arable field (looking back I had a rather unusual view of the top of Lodge Hill appearing over a green ridge, but itself then overtopped by Bledlow Ridge), then ran through two more meadows to bring me to a lane in another part of Lacey Green.

I turned right along the lane and took the second footpath on the right (it's easy to miss the first one, its fingerpost is hidden from view walking this way unless you look back). The path ran between hedges for some distance, went through a couple of gates, and continued downhill beside a large arable field on my right. It then went through a small bit of wood and crossed part of a grassy field to reach Smalldean Lane. Here I turned right, and followed the lane for two or three hundred yards to reach a small car park on the left.

I took a footpath starting from the car park, almost immediately spotting a fungus that friends later helped me identify as Velvet Shank. I ignored what looked like a path going left, then kept left at an apparent fork. The footpath was then easy to follow, with either waymarks or white arrows, as it made its way through Park Wood.
