Blue Hole (Big Pine Key)
The Blue Hole is an attraction on the island of Big Pine Key in the Florida Keys. It is an abandoned rock quarry that was used for nearby road fills and Henry Flagler's Overseas Railroad. The water it contains is mostly fresh and is used by various wildlife in the area, such as birds, snakes, alligators, key deer and green iguanas. It is part of the National Key Deer Refuge.
O'Hare station
O'Hare is the 'L' station at the northwestern terminus of the CTA's Blue Line. It is a subway station with two island platforms serving three tracks, located at O'Hare International Airport, 17 miles (27 km) northwest of the Chicago Loop. The station is located underneath the O'Hare parking garage. Trains are scheduled to depart from O'Hare roughly every 2–7 minutes during rush-hour periods and take about 40 minutes to travel to the Loop. It is the westernmost station of the 'L' system. It is also the only station without coordinates in Chicago's grid system, as O'Hare lines up with no street in the city. It is the only underground terminus, the only terminal where a premium fare applies, and is the only terminal that does not directly connect to any CTA or Pace buses. It is also one of two terminals (the other being Dempster-Skokie on the Yellow Line) that does not have a yard assigned to it (the yard is located at Rosemont, one stop east).
