One loop of Weldon Park

The quest

Walk a single loop of Weldon Park. Sit until you can name two non-traffic sounds, then leave by the same gate.

Steps

1. Enter Weldon Park 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 Weldon Park (north-west 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.
