Onondaga Lake is northwest of the city of Syracuse, New York and south of Lake Ontario. Water outflows from the lake to Lake Ontario through the Oswego River. The lake is five miles (8 km) long and a mile (1.5 km) wide. It has an area of 4.6 square miles (11.9 square kilometers) and has a maximum depth of 63 feet (19 m). Although it is near the Finger Lakes region, it is not traditionally counted as one of the Finger Lakes. http://en.wikipedia.org/wiki/Onondaga Lake
The ranking score is used to determine how "popular" a trip or location is. It is calculated based off of a weighted average of the number of reviews and the user ratings. For example, a location with 2 reviews and an average rating of 5 will have a lower "ranking score" than one with 10 reviews and an average rating of 4. This is because even though the first location has a better average rating, it has not been reviewed as much as the second location, so it is not as "popular". In the future we may modify the ranking score to take in additional factors, such as the number of views, comments, and photos.
