Well, location will get you there by itself some of the time. Other than that, you have to be conservative, know what "Cowboying Up" means and live by it, and those are about the only requirements. (My source is "The Absolute and Unassailable Rules for Being a Redneck," Honky Tonk Press, 2004)
Listening to country (especially the old stuff like Waylon and Hank), driving a truck (say, an '87 F350 quad cab long bed with a 4 inch lift kit for instance :lol: ), being a hunter, being realistic about the current state of the world, and loving the outdoors (but not like a bunny-humper) all help you along.
