Love Shetland so always enjoy
The roads you do know can be the most dangerous (getting back on subject
) being mindful not to take the road for granted.
I had a recent one, a route I use a lot, tightish left hander with banking/hedge on left meaning poor visibility. Luckily my positioning was out towards centre (about two feet from centre of road) but not as wide or as fast as some people I know take it. Coming other way was tractor with a plough on, plough bit was a good foot on my side of road so took a good bit of counter steer to get me out of harms way.
I try to learn from threads like this, taking what is good for me, and ignore the bits that don't suit my type of riding. I have a mate I don't ride with now as I don't like how he likes to hug the centre line for left handers with what appears little regard for road conditions, or other vehicles.
