What's in Mount Horeb, you ask? The Mount Horeb Mustard Museum, which was opened in 1989. Where else can you find more than 1,600 varieties of mustard under the same roof?
The Museum's founder even produces a newsletter about mustard. Its slogan? "Yellow Journalism at Its Best."
I just checked GoogleMaps -- turns out that Mount Horeb is not even an hour away. Hmmm.
