One loop of Stoney Creek Meadows

The quest

50 minutes in Stoney Creek Meadows (north of centre, London): leave the parking lot behind, pick a bench, listen.

Steps

1. Enter Stoney Creek Meadows at a public gate.
2. Walk until you have left the parking lot behind. Sit on one bench.
3. Name two non-traffic sounds. Leave by the same gate.

Why this is on the board

Parks like Stoney Creek Meadows (north of centre, London) are how London was laid out for people who do not have a cottage. One loop, one bench, two sounds — the city used as it was meant to be used.
