Pidgey Mystery Cache

As I write this, the Pokémon GO craze is at its peak, and I thought we should have our own opportunity to chase fake animals around the countryside.

The cache is not at the listed coordinates, but there are spaces to park up here to claim the cache.

Solve the puzzle below to reveal the location of the cache:

Confirm your answer on GeoChecker.com.

GPS might be a little bouncy here, but the cache itself should be easy enough to find without too much searching. I hope you brought your poké balls.

Congratulations to Sair81 and Sarasdor for a joint FTF here.
Prize for F-child-TF: a small Lego set (brand new but repackaged to fit in the cache).
