Drove by this over the weekend on my way back from a conference in Branson... not a great place to hunt.. rather small as half the "old store" is still being used. Looked like an old high school in town too, but it was fenced off and marked NO TRESPASSING. Might have to head that way some time this summer.
Interesting nugget here... I took this screen shot from Google Street View:
and then found this somewhere else:
Clearly Russell Hall Grocery sold Magnetic Water from Lebanon.
