From the authoritive Weekly World News:
A PREVIOUSLY undiscovered natural river of beer has been found deep in Germany’s Black Forest.
The existence of the Krautlager River, as it has been named, came as a pleasant surprise to most Germans as it is not even charted in maps of their legendary forest. The river of beer is believed to be the result of a fluke of nature.
We’ve got the Swan River in WA. 😀
Pity that Swan is sh1te beer.
