The Cache is not at the published coords
Bargee puzzles 1-10 are on a 2.5 mile loop through on little used footpaths through fields and along a minor road.
But first you need to take a few road trips
from Chester to Nantwich
then Edinburgh to Greenock
and Workington to Muncaster
From London to Portsmouth
then London to Bath
and Newton of Ferintosh to Ullapool
enjoy your trip.
