This easy-to-use site, developed by Duane Marden, offers statistics on over 650 roller coasters across North America. Coasters in the United States, Mexico, and Canada are currently represented. The statistics for each coaster include length, duration of ride, height and highest drop, maximum speed and g-forces obtained, and number of inversions. Each coaster's designers are also listed, and in many cases, photographs of the rides are available. One strength of the site is the searchability of the database: in addition to a quick search feature on the main page, the site offers advanced search capabilities which allow numerous fields to be queried. Also available are a helpful "tree view" that allows users to navigate a hierarchy based on geographic location, and a function that determines the roller coasters nearest to any location, based on a user's input of city, state, or ZIP code. This efficiently designed site is sure to be of interest and use to roller coaster enthusiasts everywhere.
