Tried some mountain biking tonight. Single track at night. The guys I did it with had dual suspension carbon fibre mountain bikes with a huge light on the front and another on their helmet. I had a no suspension ancient steel mountain bike that I rescued from a pole in sydney that had a tiny light that went dead around 30 mins into the ride. I had to rely on the light from the guy behind me. After the ride we were having a beer and one of them started talking about the 8 bones he had broken on a recent wed night ride on the same track. Wow, I said I was lucky not to hurt myself. One of them suggested I was fine, they made sure the guy with their stash of morphene was always just behind me….
