This cache is part of the Lenches Walk (LW) series. For full details of this mostly road-based series see “LW1 – Bend It (GC8G74M )”.
Caches are named with song titles appropriate to the location in some way. This one is named after "Don't Fence me In" by various people including Louis Armstrong, Willie Nelson, Clint Eastwood and even Roy Rogers!
We feel a theme starting to develop here - we seem unable to put out a series without including a cache at a sewage treatment plant. As we walked up we thought "here we go again". This is just a pumping station though so hopefully no aroma to deal with.
