So, rewind to that glorious morning. The sun was shining, the birds were singing, and I was feeling surprisingly optimistic about the day ahead, mainly because, well, it was a lovely day, and sometimes that's all it takes to lift the spirits. Famous last words, I know. I'd decided on the Brecon Horseshoe, mainly because I couldn't be bothered to think of anything else. Off I trotted to my usual car park in the Taff Fechan Forest, whistling a merry tune and generally feeling like I had my life together.
