I don't know what to say. Numerous posters who are runners as well as cyclists have offered their anecdotal evidence that asphalt is softer than concrete. They know this, literally, in their bones. Santaria and I have each cited engineering studies which showed that concrete is harder than asphalt by a factor of 10.

But I guess that can't quite overcome "Gosh, it sure feels hard" + "We don't sink in it" + Alton Brown's rice and salt (!).

So, acknowledging the pointlessness of continuing this discussion, I unsubscribe from this thread. Good evening, gentlemen.
