📖 The Gray Line Story: 115+ Years in the Making

It all began in March 1910, when a young Washington, D.C. restaurateur named Louis Bush transformed an old Mack Truck chassis into a sightseeing vehicle, painted it blue and gray, and started offering guided tours around the U.S. capital. His pioneering spirit laid the foundation for what would become the world’s most recognized name in sightseeing.

By 1926, Gray Line had expanded to key U.S. cities like New York, Chicago, and San Francisco—and even internationally to Toronto and Havana. After WWII, Harry J. Dooley, a visionary former employee, re-established Gray Line in Chicago and later became its president. He is now celebrated as the father of the sightseeing industry.

In the postwar travel boom of the late 1940s and 50s, Dooley expanded Gray Line across the U.S., Canada, Mexico, Hawaii, and Puerto Rico—solidifying its status as the leader in motorcoach and guided travel.

In 2011, Gray Line celebrated 101 years in business, marking more than a century of delivering unforgettable travel memories. Today, we continue to evolve with modern technology, sustainable practices, and innovative guest experiences—while staying true to the mission that started it all: helping people explore the world, one experience at a time.
