This is full of hot air
Every year, during the last week of January, the Swiss alpine village of Chateau d'Oex (pronounced "day") organizes a Hot-Air Ballooning event with hundreds of colorful balloons participating from many countries. Rides unfortunately costs a bomb.
These were shot with a 70-200 mm f/2.8 L IS and 24-70 mm f/2.8 L. The two best lenses that any Canon owner can have.
