I was looking for a good 4th of July story, so the first thing that popped into my head was Captain America. While browsing all of the early covers of Captain America I found all of the expected foes of the Captain: Hitler, monsters, Tojo, zombies, robots, and the like. But then I came across issue #11 above which features Captain America trying to save Bucky (who seems to be the most useless sidekick in all superhero history) from the "horror of the feuding mountaineers!" And of course these hillbillies don't wear shoes, can't shave, reject dental care (in any way shape or form) but are all armed to the teeth!
The mountaineers are of course a reference to the infamous Hatfield-McCoy feud. Although I think seen in the context of 1940s America the poorly groomed hillbillies are seen to be the enemies of progress, science, modernism and thus America itself. One would think that the leasure suit movement of the 70s made the nation safe for casual fashion statements, but alas the anti-mountian man movement may be back in full swing again...
