The cache is not at the published co-ords, they are just for a random bit of road so won't help you at all. Cache isn't too far from co-ords though.
This sneaky little nano is located by the side of a very quiet road and is chest height (for me whilst standing) so everyone can grab the cache even those in wheelchairs. As it is a nano it is going to be tricky to find and there's no hint to maintain the difficulty of 5.
The puzzle is quite appropriate for me and those of you who know me this may give you a small hint.
To find the location of this cache you need to work out the following puzzle:
N51 (butterfly - badger) (bumblebee - walrus) . (bear) (eagle) (penguin - elephant)
E000 (squirrel - elephant) (eagle) . (flamingo - squirrel) (penguin - eagle - elephant) (walrus - squirrel)
Good luck :)
