This is a Bonus Cache for the Old Wakefield #2 Adventure Lab. The Cache is not be at the posted coordinates, but may be found at:
N 53 40.ABC W001 30.DEF
The Adventure Lab is in a small, historic, area of Wakefield and, wherever you finish, you will not be too far from this Bonus Cache. However, if you want to reduce your walking, I suggest that you finish at the Orangery.
As always, stealth may be required, and please take care to replace the cache as found.
Congratulations to HotHeads33 on being FTF.
