Area students will deck the halls of Washington Dulles International and Ronald Reagan Washington National Airports for their sixth annual tree trimming celebration. School children from the District of Columbia, Maryland and Virginia will decorate trees with “Home for the Holidays” theme-related ornaments, which will be on display for passengers and visitors to enjoy during the month of December. Last year, more than 250 students from local schools participated in the “Celebrate the Holidays on Candy Lane” themed tree trimming at both airports.
