Another Tunnel

Geocaching days out with R usually involve tunnels or trees. Today was definitely  a tunnel day. Its. perfect weather for tunnel exploration because we haven't had rain for about seven weeks and all the rivers are low,. This is the entrance to a tunnel under the M66 near Ramsbottom. 
R has made a collage of the tunnels  we visited, of course with me in . See here if you want to see inside a tunnel
