Furzedown is a family neighbourhood between Tooting and Streatham. It's home to the Mayor of London Sadiq Khan, and Graveney secondary school.
The Recreation Ground - known as 'The Rec' to locals - is a small park in the heart of Furzedown. There's a playground, two tennis courts, a basketball court, skate park and a ping pong table.
The cache is a magnetic nano, hidden somewhere in the park. You'll probably need tweezers to get the log out. Enjoy your visit.
