I've just discovered that there's an Intercollegiate Quidditch Association with over 200 teams! For a slide view of some of their games, click on the link.
Here's what their website says:
The IQA started in 2005 as an intramural league at Middlebury. The rules were adapted from JK Rowling's Harry Potter novels by Alexander Manshel, the first Quidditch Commissioner.
In 2006, Alex Benepe took over as the Middlebury Commissioner, and in 2007, he founded the IQA, following the first Intercollegiate Quidditch match between Middlebury College and Vassar College on November 11th, 2007.
Since then, more than 200 institutions from around the world have joined the league. The vast majority are based in the US, and are divided among five regions: The Northeast, Southeast, Midwest, Southwest, and Northwest. Other countries with teams or leagues that play by the IQA rules include Canada, Mexico, Argentina, England, Iceland, France, Israel, and Australia.
Additionally, dozens of High Schools around the world have started playing by the IQA rules as well. In an effort to standardize the rules as much as possible, the IQA will distribute its official rulebook to any team, of any age, representing any institution (clubs and community groups are allowed as well) in any country of the world. Currently the rulebook is only available in English, but that will change soon.
WOW. I think I'll go back to college. It looks like more fun than the standard football/ soccer/ whathaveyou games.
