Think broader in your choices for majors. These days, most planners have a graduate degree in city / urban planning. This means regardless of where you go, you likely will go on to graduate school. Luckily UNC-CH has a top city and regional planning program. I would aim for getting into UNC’s graduate program for city planning.
Many people who study city planning at the graduate do not have a planning background. I had majored in math and design. Others majored in political science, architecture, religious studies, economics, history, civil engineering. Older students came in with law degrees. You get the picture. Very very few had majored in planning or even urban studies.
As for leaving the state, again think long term. UNC-CH has a national reputation. People I know who got their master degree from UNC work and live in New York, Washington DC, Washington state, Illinois (Chicago), California (San Jose, San Francisco, LA), Florida, New Hampshire.
