I was riding rather spiritedly to work at the dealership one morning, on a narrow, very twisty, sun and shade dappled road in Western Pa, that I knew like the back of my hand, when I slid sideways in a curve. Both tires slid. Thankfully, I didn't panic, got lucky, and the tires hooked up, and I continued on my way. I went back to see what had caused the slide. In a dark shady area, there was a fresh patch of tar and pea gravel. They didn't do the entire road surface, just patches, and put up no signs. Unbelievable. I ride the Concours on gravel a lot, in PA and in Iowa, and I'm okay with it, because I know what it is, but patches of tar an pea gravel, not knowing? I really hate that.
I am happy you both are okay. It could have been worse. I really hope the idiots in charge learn to place signage on the roads they treat like that. One road within a quarter of a mile of my house was just tar and chipped. They have signs up though, and it is obvious since they did the entire road surface. They used chips too, not pea gravel, which isn't a slick.
