The Box Hill run brought back memories...
As a kid we used to go there for a picnic with Mum and Dad.
Must have been the early/mid 60s.
Mum had made some jam tarts, they were in a round cake tin.
I played with the tin, rolling it down a bit.
Ooops, let go.
It rolled down the hill, the lid came off and the jam tarts rolled out, breaking up as they went.
I was NOT popular, and have never been back.
