Arthur helped me to put this cache together, providing several
of his own toys for the initial cache contents. One even became,
via the use of a drill, a travel bug!
There are several ways to access the cache, but one way involves
parking near N 51°27.664' W 003°18.671'. You'll need to
exit onto the "road" at N 51°27.736' W 003°19.087' (which
might point you to an alternative -- but less interesting --
parking place).
I normally recommend the use of an OS map and compass, but it is
quite possible to navigate to this cache without (especially if you
make use of the nearest available parking spot).
