Lynwood Road recreation ground has two large open spaces - one with football pitches and the other with a nice children’s playground. Regular trains whizz by the different tracks surrounding the area to and from places like Hampton court.
This is another small, magnetic and well-concealed nano-cache with a frog on it. Carefully hidden behind a redundant post. You will need your own pen and tweezers to remove small log.
UPDATED: I try check on this cache most days while dog-walking. I keep finding it on the ground having fallen off. The magnet isn't very strong so PLEASE WIPE THE BASE DOWN BEFORE REPLACING AND REPLACE IN SAME PLACE (and avoid being seen by any muggles who might be heading to the park). Thanks :)
