I was riding on a road that I had never been on before when I hit a stretch of road that caused some concern. The entire road, all three lanes, had grooves dug into the surface going in the direction of travel. They were not extremely deep, but they were an inch or so apart and an inch or so thick. While it wasn't a rough ride at all it did cause the front end to feel a little squirly. Kind of like the front in was sliding back and forth. Has anyone experienced this before? Any tips on riding on a surface like this? I just slowed way down, and slid over into the slow lane. It only lasted a couple of miles, but I never did feel real comfortable.
