Never done it on 2 wheels, but having raced many shale tracks in a car I can honestly say it was the most enjoyable. Yes it is fast, yes it is narrow, yes it was messy if you got it wrong. But also, yes it was exhilarating, and it gave immense satisfaction when you got it right.
I think the problem when it comes to opinions on tracks on here, and this is not meant disrespectfully, but people who have never raced anything will never understand the mindset of a racer. The risk element is part of why you do it and there is a lot of pleasure in conquering that danger.
