In March 1910, a young restaurateur named Louis Bush refurbished an old Mack Truck chassis. He painted it blue and gray and then began offering sightseeing tours around the city of Washington, D.C which then became the world’s leading sightseeing tour company, known today as Gray Line. The company is into local sightseeing tours activities and travel packages using trolley coaches and double-deckers. They are also into charter services, airport transfers, and convention services.
