You are quite right
but wooden chips are more dangerous as compared to nails due to the area covered. And they can easily puncture tyre and Keel to Taobat track is full of those chips 
Exactly !! There's no fun in trip unless you have one flat tyre, that why i wrote that adventurous opening post 
Lol.. You cant go there before June-August as the whole area will be covered from snow. People cover distance on foot from Keel-Taobat
