Innocent Railway

To keep up my geocaching streak today I headed to get an easy geology based cache which just required me to answer a simple question. As I was near the innocent railway, and I had time, I chose to try and find one in the tunnel that I thought would be tricky.

Using your GPS in a tunnel doesn't work and by looking at past logs I knew I may struggle. I paced from both ends and didn't get to the same location but luckily, at the point of giving up, I found it in the section in between. Lots of commuters cycling past would have wondered what I was doing.
