Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Hey Golden, I was invited to your ABAB group, but I'm not at all sure what's it's purpose? I scrolled through the threads but I couldn't find anything :/ What's it all about?
This particular photo (not mine) is from a roller coaster called "The Incredible Hulk" at Universal Studios Islands of Adventure in Florida. I've never ridden it, but chose the picture because it was the best example of a cobra roll I could find. http://rcdb.com/557.htm?p=0
