Florence - Sunset over Arno by Giuseppe Torre :( I miss it SO MUCH. And I must get back here someday so I can get to the top of Il Duomo, and watch the sunset on the Arno from the top of San Michaelangelo.
Piz Gloria / Schilthorn summit, Switzerland with the revolving restaurant famous from the James Bond film website. The views are spectacular; check the webcam online to make sure the weather up top is clear before you go. The Bond movie is a must-see!
