If you're not doing the full Weedonhill Wander, you can get to this cache more quickly by parking up at the original, unsolved coordinates for Pidgey.
You're looking for a small clip lock box.
Congratulations to Brian Ze Owl for claiming FTF here.
Honourable mention to Sair81 and Sarasdor for second place shortly thereafter.
Prize remaining for the next child to find: a small Lego set (brand new but repackaged to fit in the cache).
