Hello, I'm Astros4477. I noticed that you made a change to an article, Roller coaster elements, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you.  Astros 4477  ( Talk ) 18:00, 5 March 2013 (UTC)
