Undergraduate history is not really the same as graduate level work. Many states recognize this by requiring at least an MA in history to teach in public schools - you'll have to check out Arkansas's requirements. Either way, if you really want to teach history, and you want to do a great job at it, I'd suggest you look into graduate school options. There are plenty of universities not in large towns that offer history graduate degrees.

You can also look into public history positions - think museums or historical sites. Depending on the demand for the jobs, these might be easier to obtain with only an undergraduate degree.
