Watch the sun drop from Medway Valley Tral

The quest

Medway Valley Tral faces the last light north-west of centre, London. The quest is standing still until three lights stay on after the sun.

Steps

1. Arrive at Medway Valley Tral twenty minutes before sunset. Stay on public ground — not a bike lane, not a road deck.
2. Watch until the disk is gone. Name three lights that stay on.
3. Leave the way you came. Do not climb railings or cut through private docks.

Why this is on the board

Medway Valley Tral is one of the spots north-west of centre, London where London actually faces the sky. You get the last colour of the day and a few minutes of standing still a patio will not sell you.
