Some day, Dallas will boast an extensive network of dedicated bike lanes that will allow riders to get anywhere in the city without so much fear that the side mirror of a speeding F-350 will send them to an early grave. That day is far, far away. The city has a plan for such a system but has been dragging its feet and has done exceedingly little to see it through. The only sign of progress came earlier this year when the city unexpectedly laid down its first shared bike lane on Martin Luther King Jr. Boulevard between Fair Park and Julius Schepps Freeway. The person, if he or she exists, who commutes between those two places on a bike is no doubt thrilled. For the rest of us, it's a sign that the city might eventually become bike-friendly. Someday.
