Who would be the best person to hire as DC Dept. of Transportation director?

I'm not sure. I'd probably ask Chris Zimmerman. Oh, he's on the Arlington County Board, and currently chairman of the WMATA board. But he is probably the best elected official in the region on these kinds of issues...

Via the WMATA press release, "Metro announces key appointment: Organizational changes include establishment of new Chief Administrative Officer" and the DDOT press release, "Fenty Names Interim DDOT Director."

DDOT director Emeka Moneme will become WMATA's Chief Administrative Officer, and Mayor Fenty has appointed DDOT general counsel Frank Seales as interim director. Regardless of his experience, having a lawyer running the Department of Transportation doesn't do the need and necessary vision "justice."
