Olga will take us on a walk. From her email:

We are going to have a very local walk as it starts getting dark about 8.30 – SO…

Meet by the main entrance of Park Hill in Barclay Road (near the Magistrate Court) at 19.30 

We will walk through Park Hill and then towards Lloyd Park. It is going to be an easy and relaxed three miles walk.

On the way back we can go for a drink to The Porter and Sorter near East Croydon station.
