Wow! That was one informative video. Thanks for posting it.
There was a film several years ago called "The Road to Wellville" (or something close to that) with Matthew Broderick and Dana Carvey and several other well known actors ( who I can't recall). The film was centered around this resort of Kellogg's and apparently has several elements which are apoarently historically accurate.
@RussRAB I almost pasted a link to it, but on second thought I assumed people would think it was fiction.
@Willow_Wisp - The video you posted was great! The film I mentioned can only be considered historical fiction at best. The one you posted had lots more detail and facts. You made a good choice.
