Gather a letter and a number from this cache to find the Bonus cache.
To find this cache: Start at the above co-ords, where you'll find an oval plaque on the bridge, easily seen from the bridge itself. It looks like: (where letters are letters and symbols represent numbers you need)
NAJ%
$?
%&m !£ch
% = ___ | $ = ___ | ? = ___ | & = ___ | ! = ___ | £ = ___
To locate the cache at this end of the series, head to:
N51° 4((£-?)+!).($-£)(%x$) W000° 5(?-(%+&)).$(%+&)(&-!)
To reach it, you'll need to walk - or better still, given the route - cycle a little way. Good luck! Fun fact. The large house beyond the church - Horsenden House - is home to Jay Kay of Jamiroquai fame. So if you're passed by a Ferrari on this road, don't be too shocked and try to act cool.
