Admittedly there was a time when local "wars" were actually waged over proponents of open range for cattle and fenced farm yards for chickens, pigs, and crops. And in fact, the most famous movie filmed against the backdrop of the Grand Tetons, Shane, is a story built around just such a conflict.
The best-known version of "Don't Fence Me In" was written by Cole Porter in 1934 for the film, Adios Argentina, and wasfeatured subsequently in many other movies -- and sung around countless campfires ever since. Wikipedia offers a good little history of the song, including information about the original lyrics on which Porter built and the place of the film in popular culture. Here are the familiar lyrics:
Oh, give me land, lots of land under starry skies above
Don't fence me in
Let me ride through the wide open country that I love
Don't fence me in
Let me be by myself in the evenin' breeze
And listen to the murmur of the cottonwood trees
Send me off forever, but I ask you please
Don't fence me in
Just turn me loose
Let me straddle my old saddle
Underneath the Western skies
On my Cayuse
Let me wander over yonder
Till I see the mountains rise
I want to ride to the ridge where the West commences
And gaze at the moon till I lose my senses
And I can't look at hobbles and I can't stand fences
Don't fence me in
