You are looking for a small plastic pot which has been expertly camouflaged. There is no room for trackables and you will require a pencil.
muggles aplenty here so stealth is of the utmost importance. The recreation ground can get very busy so try and pick a quiet time for maximum chance of success.
parking is available close by so would make a nice cache and dash.
good luck!
