I've included the original cache description, decrypted hint and co-ordinates below as a hat-tip to the original cache owner. The co-ords I have listed are from a GPS reading at the time of hiding.
"A truly terrible movie but a great hang out from my youth.
This was the place to be in Belfast if you were in to BMX riding, one of the early BMX tracks. Hubby has many a good memory of hanging with mates, long summer days, skinned knees and watching the action. Sadly the glory days have passed but you can make out the remains of this once great track. Cache is a smico ( a cross between a mico and a small) camo'd to help it blend in. Care is needed when retrieving and replacing cache.
Additional Hints (Decrypted)
Not even Nicole Kidman on her BMX could reach this"
Original Co-ordinates: N 54° 33.134 W 005° 56.114
=======================================
The cache has been replaced. It is now a bison inside a larger, camo'd container. It is tied to the tree and there is no need to untie/remove the outer. There is no-longer a pencil inside so please bring your own.
Please take note of the difficulty and terrain and be careful when retrieving the cache - not just for your own safety but also because there can be a high muggle footfall in the area. Every time I've been at GZ people have passed walking their muggle-mutts.
