Really dumb mistake here.
Went to a new place on my brand new bike (Pudeltown woods) at the car park met a young chap on something really not very noteworthy and he offers to show me round, ok off we go we do some fairly techy single track nothing to hairy and end up on a gravel road that has a steep drop hidden to my right he turns in between some bushes and I just follow there is a near vertical drop to a plank bridge a bout 6/8 feet above a bomb hole, little narrow bridge and i collide over the bars and over the side of the bridge i go he is off in the distance when I wake up I have 3 crushed vertebrae.
learnt an important lesson that day about knowing trails and trusting people.
