Marc Fisher gives driving to the ballpark the Dr. Gridlock treatment. I drove to the ballpark during rush hour this morning, using the following route from the mid-city area: 9th Street NW/SW to Maine Avenue SW to M Street SW to First Street SW. Parked on the unit block of Q Street SW; crossed South Capitol Street at Potomac Avenue and strolled right in. Door-to-door time? 20 minutes. —Mike DeBonis
