One loop of Batting Cage

The quest

Batting Cage (north-east of centre, London) is larger than the postcard. One loop, one un-famous bench, two sounds that are not traffic.

Steps

1. Enter Batting Cage 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 Batting Cage (north-east 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.
