I was riding the other day on one of those roads where the top layer of blacktop has been ripped off for repaving. And all that is left are these lines of concrete that are constructed in wavy vertical lines. It made me feel like i was going to go down at any time. I was slowed down to about 35 and it was still terrible. Anybody else ever have to ride on one of these. They're a serious safety hazard in my opinion.
