I can't believe this news! If you never had the chance to take one of their tours, you're out of luck now. The company that runs Chicago’s famous red double-decker tour buses is shutting down after 25 years in business. For 25 years their trolleys and double decker tour buses guided tourists (and residents who just wanted to enjoy the city from a different view!) up and down the Magnificent Mile, and all around some of the city's most beautiful landmarks. Tourists, ticket holders, and even employees were caught completely off guard by the sudden closure with little notice. The company has not provided the public with any specific details behind the closure.
