One of the roads on my commute has a two mile section that until recently was dirt/gravel. Then about five years ago, a large housing development was put in with access to that old road. So it got 'paved' by throwing down some tar and stones. No foundation, just tar and stones. Of course with the construction traffic, that old farm road got beat to death. It is murder to drive in a car, much less a road bike with skinny high pressure tires. My only other option is to ride on a 'pedestrian and bicycles prohibited highway. I just have to grit my teeth and hope that nothing gets rattled off the bike. My rear blinky was not up to the challenge, and pieces-parts went skittering into the weeds....
