WORLD'S HIGHEST TENNIS COURT

HIGHEST-TENNIS-DUBAI
Yes the picture's real. Burj Al Arab in Dubai is home to the world's highest tennis court (at times).
At 210 meters (about 690 feet), it's pretty far up there.

Way higher than I'd feel comfortable running around hitting a ball. The court doubles as a landing pad  when there aren't any matches being played, and as a place to shit your pants the rest of the time.
