There are plenty of rewards along section 19 of the Loop though, lots of lovely little semi-secret passageways that nip between people's houses. I bloody love a semi-secret passageway and always get disproportionately excited to find a waymarker pointing to the side of someone's garage or behind a shed.
We are also, obviously, still basically in London so you also get caged-in railway bridges covered in graffiti. Chingford graffiti quality = low.
