Where can I legally practice with my shotgun?

I live in New Hanover County, NC and was wondering if it's legal to go into the woods outside of any incorporated towns and shot a shotgun. I found a public gunclub around Southport (about 45 miles away) that costs $20/day. I would like to practice for free a lot closer to home, if that's possible. Any information would be appriciated.

It's most likely fine provided you have landowner permission, but you should check the area for yourself. A call to the Sheriff's office should tell you what you need to know.
