Well, now, the mail contains a notice that the Pennsylvania Avenue Corp., the government's main-stem redevelopment agency widely known by its PADC initials, has moved its office onto Pennsylvania Avenue--although some purists such as Metro Scene would say it's really on E Street, the 1300 block of E Street that was illegitmately given an Avenue designation recently by the D.C. City Council.

Whatever the now-futile arguments on that, PADC has sent one of the most riveting change-of-address notices on its move from the Pennsylvania Building, 425 13th St. at the corner of Pennsylvania Avenue, to 1331 Pennsylvania Ave.

"Once upon a time did PADC speak to the owners of the Pennsylvania Building saying 'Yea, verily, thou shalt totally rehabilitate for a greater Pennsylvania Avenue,' " wrote PADC Executive Director M.J. Brodie. " 'Forsooth,' respondeth the owners, 'we are ready to leave if PADC and others leaveth by March 31, ye last day of ye lease.'

"Well, some say it couldn't be done. And some were almost right. But we reached 13th Street, and the waves of traffic parted, and we crossed over into dry land. That was the easy part.

"Now, as we dig through the countless boxes . . . we've discovered . . . 12 developers . . . 11 architects . . . 10 planners . . . 9 contractors . . . 8 subcontractors . . . 7 suppliers . . . 6 Office of Management and Budget examiners . . . 5 General Accounting Office auditors . . . 4 congressional staff . . . 3 previous executive directors . . . 2 investigative reporters, and a partridge in a willow oak tree . . . .
