The group was hosted by Harford County Executive David R. Craig, who was involved with the sister cities exchange program when he served as mayor of Havre de Grace, according to Bob Thomas, spokesman for county government.
Among their stops locally, the visitors attended a public meeting at the Bel Air Armory, where Craig was joined by members of the Harford Office of Economic Development, representatives from the Town of Bel Air and other local and state elected officials.
Among those visiting from Estonia were Ulle Rajasalu, Harju County governor; Kaarel Kose, division advisor, Harju; and Terje Lillo, advisor to the governor of Harju.
Rajasalu, as a county governor, holds a position similar to Craig's.
Harju is one of 15 counties in Estonia. Although the county is small in size and population, Harju's population of almost 550,000 is more than double Harford's population and accounts for nearly 40 percent of Estonia's citizens.
Harju also has several municipalities, the largest of which is Tallinn, Estonia's national capital.
