American Coaster Enthusiasts (www.aceonline.org)

Hilarious in my opinion. My friend Graham and his wife April just stopped by Brian & Christine Virtue's place where I am hanging and we heard some fun stories of his mom and sister and the group of roller coaster enthusiasts they belong to. His mom has ridden over 550 different coasters all over the world. They plan their vacations around coasters and when traveling to Europe they didn't visit the Eiffel Tower or other historical and famous locations--they visited coasters. You can visit their website posted above. I laughed so hard hearing their stories.
