If you think that A&W, Hires, Barq's, Mug, and Stewart's are the only root beer games in town, then think again. Root Beer World, http://www.root-beer.org/, which proudly proclaims itself to be "a world of root beer resources," lists thousands of unsung brands as well as message boards for root beer enthusiasts and root beer recipes (root beer torte or Robert E. Lee cake anyone?) As for this picture of a root beer-themed Snoopy tale, it's just one of the many sarsaparilla-spiked stories featured in the aptly named "root beer books" sidebar section that appears on the site's various pages.
So why am I writing about a soft drink? Because I like it. And because the link for http://www.root-beer.org/ has been burning a hole in my favorites list for the better part of a year since the bf discovered it (he has a knack for such things).
