THIS CACHE
This is a very short multi, maybe the shortest you've ever done. 
The container is a micro. Note the terrain. A solo cacher will have great difficulty getting this unless they have additional equipment,
The coordinates bring you to a solid sign with just 4 words and 4 numbers on it. Let the date = WXYZ. The Final is N54° 01.ABY W6° 13.ACD
These are calculated as follows :-
A = X - W
B = W x 3
C = (X - W) / 2
D = X - Z
Check sum for A + B + C + D = 15
THE NEXT CACHE
SFC02. Continue up the trail directly in front of you. You will find the start of the whereigo a very short distance in front of you.
THE SERIES
Parking is available for a couple of cars at the coordinates given for SFC01.
This is one of 12 caches on a circular walk on the lower slopes of Slieve Foye (SFC = Slieve Foye Circular). It is designed to be walked in a clockwise direction. It starts on good track, passes through muddy trails and eventually becomes open mountainside before returning to good track to finish. Its approximately 6.5km and you will gain about 200m in height. The middle section can be boggy. As with all hill walking conditions can change quickly so dress appropriately.
Only SFC01 and SFC03 are dog friendly. Motor Bikes, ATVs and similar are all banned from the mountain,

REPLACEMENTS
NO THROWDOWNS. Specific hints and spoiler photos are provided for all the caches in this series. My intention is that if you make the effort to walk the series then you should make the find. If you believe the cache is missing and you had access to the spoilers during the walk log a maintenance request. If the cache is missing you will be contacted with an offer to log when it is replaced.
If you have forgotten your pen (as a cacher you should be ashamed of yourself), photo proof of your visit will do. I have no objection to additional spoilers on any cache in this series.
