The windy city of Chicago is full of interesting things to see and do.

Including something many do not know about. Hidden passages.

In an article from Drive the Distance, Chicago has over five miles of underground passages that you can take from the airport (either Midway or O’Hare) to the Hyatt Regency in the city.

You can stay underground to get a a haircut, shoe shine, spa service, do your banking, pick up flowers or get a nosh, while traveling in between 50 buildings in the downtown area.

The Chicago Pedway offers tours of this city's hidden gem, not even many of the locals know about it. No matter what the weather outside, inside it's warm in winter and cool in summer. No wind, no snow, no rain no heat to deal with.

The tours aren't logical or on a straight route, as the segments were developed in a piecemeal fashion from several different building owners. Although it might seem a bit choppy it sure to be interesting. A tour could take you underground from Wacker, just south of the Chicago River, to Monroe, the base of Millennium Park, and east as far as City Hall and the Thompson Center, . After all, the pedway was developed piecemeal, with individual segments planned and operated by the owners of the buildings above it.

Wow! How cool is that? I'd do this. Would you?
