Very neat, especially for the 20's.
New stuff is quick, but maybe a little less flexible.

In September of 2009 cyclists from around the world will gather on SR305 outside of Battle Mountain, Nevada for the 10th consecutive year to race on one of the straightest, flattest, and smoothest surfaces in the world. The 4,619ft (1,408m) altitude road allows riders an acceleration zone of over 4 miles, enabling them to reach their maximum velocity before being timed over a 200 meter distance. The section of the road that we use will be newly refinished this year, with a smooth surface specially prepared for this event by the Nevada Department of Transportation.
