This is #2 in the series 'Benji's Walk'.
You are looking for a medium sized clip-seal box.
Those with young children may want to do #1 and #10 as a drive bys and then do the rest of the walk from here, as there are no busy roads to cross then, I have created a way-point for the playing field car-park.
Due to some new fencing you will have to exit out of the spinney the same way you came in, and then follow the footpath left across the fields towards Grange Road and #3 in the series.
