Seattle is located between the saltwater Puget Sound to the west and Lake Washington to the east. Seattle's economy is driven by a mix of older industrial companies, and "new economy" Internet and technology companies, service, design, and clean technology companies. The Port of Seattle, which also operates Seattle–Tacoma International Airport, is a major gateway for trade with Asia and cruises to Alaska. It also is the 8th largest port in the United States when measured by container capacity. Among Seattle's prominent annual fairs and festivals are the 24-day Seattle International Film Festival, Northwest Folklife over the Memorial Day weekend, numerous Seafair events throughout July and August, the Bite of Seattle, one of the largest Gay Pride festivals in the United States, and the art and music festival Bumbershoot, which programs music as well as other art and entertainment over the Labor Day weekend.
