Irondequoit Bay is a large body of water located in northeastern Monroe County, New York. The bay, roughly 0.5 miles (0.80 km) wide and 4 miles (6.4 km) in length, is fed by Irondequoit Creek to the south and flows into Lake Ontario at its northern end. On average, the surface of Irondequoit Bay rests at 245 feet (75 m) above sea level and is 68 feet (21 m) deep at its deepest point a short distance north of the Irondequoit Bay Bridge carrying the six-lane New York State Route 104 over the bay. http://en.wikipedia.org/wiki/Irondequoit Bay
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.
