Rondout Creek is a tributary of the Hudson River in Ulster and Sullivan counties, New York, USA. It rises on Rocky Mountain in the eastern Catskills, flows south into New York City's Rondout Reservoir, then into the valley between the Catskills and the Shawangunk Ridge, where it goes over the spectacular High Falls and finally out to the Hudson at Kingston, receiving along the way the Wallkill River. http://en.wikipedia.org/wiki/Rondout Creek
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.
