For a general description on the series please refer to the text for the 'Two Trails: 1'
At the published location find the answers to the following:
a) The number of planks making up the seat = A
b) The number of vertical metal posts supporting the structure = B
c) The number of longer horizontal rails supporting the roof canopy = C
Place the answers into the following to give the final location of the cache: N51 47.C(B-B)(C-A) W002 B0.(A+C)A(B-C)
NB: Shortly after obtaining the clues you will be walking along the side of the busy A466 road, for about two hundred metres, with only a narrow unmade footpath, so care is needed especially with children and dogs.
NB: Just a reminder that after this cache, you need to look out for clues in the caches for the bonus cache.
