If there was one mystery few District residents and visitors ever managed to solve, it was the city’s infamous taxicab zone map. Geographically confusing and lacking in detail, the map was supposed to give passengers a hint as to where one zone ended and the next began, though it usually resulted in a headache and a feeling of dread that the $10.30 in change you had scrounged up wouldn’t be enough to get home.

But thanks to Mayor Adrian Fenty’s “100 Days and Beyond” action plan, the District Department of Transportation has spiffed up the old map. Beyond a clearer demarcation of the city’s zones and the major streets that bound them, the map features D.C. in its proper directional orientation — north is up, south is down. Gone are the days you’d have to crane your neck sharply to the left to get your geographic bearings straight. The map also features updated fares and major historic and transportation-oriented landmarks.

Unfortunately, some zone boundaries still remain vague, and may become even more so when you have to stare at a miniaturized version of the map in the back of a cab on a bumpy road after a few beers. Ugh. We’re dizzy already. But we guess this is a baby step towards what we’re hoping Fenty is going to push during his second action plan, aptly titled “The 1360 Days Until Re-Election”: meters.
