A 64-year-old landmark has disappeared overnight from Main Street in Upper Marlboro, the Prince George's County seat.

After the exodus of county and courthouse workers one night last week, wreckers went to work on the Suburban Trust Co. bank building. By morning, the old building was rubble.

The one-story structure, built in 1919 to house the Marlboro branch of the Southern Maryland Trust Co., faced the county courthouse.

It stood squarely in the path of a projected brick walkway that will eventually link the courthouse and the county administration building.

While the walkway and a partial closing of Main Street along with it remain in the future, the branches of government now have a relatively unobstructed view of each other.

Marlboro, as the town is called by almost everyone who lives or works there, is changing. Until 1977, virtually the entire county government was jammed into the courthouse, and the modern government office building rising by School House Pond seemed but a surreal symbol of the future.

Still to come: A "ring road" around the town and a multipurpose state office building that also will consolidate the District Court into one location.

That was a BMW with Maryland tags that brought AFL-CIO chief Lane Kirkland to Channel 4 to lament, on "Meet The Press," the plight of the American auto industry. (AFL-CIO parking sticker No. 105.)

In an effort to atone for a planning error, State Sen. Leo Green (D-Bowie), sent notes to persons with Jewish names who were invited to his annual fund-raiser last Saturday, promising that next year's event won't be held on Yom Kippur.

"I hope that receiving it a ticket did not offend you," Green wrote. He explained that the party was held on the Harbor Queen, a boat that is usually booked nearly a year in advance, and in the confusion of the campaign for his legislative seat last fall "we didn't act soon enough."
