In addition, look for "Visitor Information" or blue question-mark signs near your destination. They are on all major highways and, especially in Frederick and Western Maryland, will lead you to an office filled with knowledgeable people. Maryland Welcome Centers are on I-95, Route 50, Route 68, Route 70, and Route 301, as well as at BWI Airport.
