Chicago from above

Following a recent renovation, the new Hancock Observatory invites you to enjoy Chicago’s best views from the city’s highest open-air Skywalk. It has quickly gained (POPULAR) with both Chicagoans and visitors of the city.
Skywalk is Chicago’s highest open-air viewing area. It is 1,000 feet in the air! Everyone here can feel the strong wind and hear the dynamic buzz of the city below. The friendly staff will (CERTAIN) tell the real story behind Chicago’s “Windy City” nickname.
For those who feel (COMFORT) about such a great height there are more relaxing indoor audio Sky Tours. These 30-minute personal audio tours give a unique “overview” of Chicago’s wonderful sights and (REMARK) history! Sky Tours are available in English, Spanish and German.
History Wall is another popular (ATTRACT). More than 100 photos on a great 80-foot display show Chicago’s rise from a small settlement to a great city. As a tour guide I have been to the Skywalk (COUNT) times and still I can't help admiring it.
