Prince George’s County, which is trying to position itself as the next big thing in the Washington region, took its road show to the 43rd annual Congressional Black Caucus this weekend, holding a meet-and-greet reception that drew about 300 guests from around the country.

Prince George’s is eager to attract new businesses with its $50 million economic incentive fund and is trying to bring major federal installations such as the FBI to the county. So every bit of exposure helps, said Barry Hudson, a county spokesman.

While the Friday night meetup, hosted by County Executive Rushern L. Baker III (D), attracted such Maryland luminaries as Attorney General Doug Gansler (who is running for the Democratic nomination for governor) and U.S. Rep. Donna Edwards (D), it also lured politicians and the curious from many other areas, Hudson said. This is the second year the county has held the reception.

“Last year we were mostly talking to ourselves,” Hudson said. “This year, it had a different feel.”

While partygoers waited in line for food and drink, they had a chance to glance at art work by county residents, as well as photos of FedEx field, National Harbor and Six Flags, Hudson said.

The $19,000 tab was picked up by Care First Blue Cross Blue Shield, Cambria Solutions and Veolia Transportation, which has a bus system contract with the county.

It’s the second time in recent weeks that CareFirst has underwritten a Prince George’s project. In August, the company was a major donor to a $2.3 million health-care clinic in Greenbelt for low-income patients.
