Root Beer Cheer

I don't drink soda often, but I love me some root beer.  I think all pizzerias should be required to have root beer on tap.  I saw a girl on the L train platform yesterday with a box of Thomas Kemper root beer and almost worked up the nerve to ask her where she got it.  For those of you who've never had the pleasure, Thomas Kemper makes the finest root beer I've ever enjoyed, with a nice foamy head and full body usually associated with dark alcoholic beers.  It's brewed by the Pyramid Ale folks out in Seattle.  They also make an excellent orange creamsicle sody. 

Here is a list of internet retailers who'll ship to New York.  But how cool would it be to show up at a barbecue this summer with a pony keg of root beer and a gallon of ice cream?
