I'd say this is the item I have the hardest problem with. I tend to look about 50' out, scanning for bad juju on the surface. Sure, I look way out, but I look in, then out, then in, etc.
Now, I'm going to interject tar snakes into this. I had a slip that scared me silly this year. I was cornering, not going too fast, but leaning a bit on my RT. Hit a snake that let the bike shift over enough that my feet came off the pegs & soiled my shorts.
From then on, I kept looking down, tyring to put my tire between the snakes, boy my confidence went down hill then. I could not bring myself to trust the tires & look down the road any more...
How do you get back from that?
